i am a an architecture student in final year, and for thesis i want to study the how pandals and tents with fabric affect the spatial experience
New styles in architecture are often created along with the changing requirements of the world and social and cultural life.
It is also related to the invention of new building materials.
An example is Secession (aka Art Nouveau, Modernissmo), which arose, among other things, as a need for expression in new building materials such as steel and concrete.
Do you think that AI and the solutions created with its help can contribute to the development (creation) of a new style in architecture?
How would you call this new style of architecture that is combined with Artificial Intelligence?
I want from you, my friends, ideas and suggestions for new building materials to change people’s perception of building
The principles of improving the existing seismic resilience have the ability to adapt to new cities. I need the frameworks and principles that are used to improve the resilience of historical cities according to their unique characteristics (such as the density of buildings - street patterns - building materials and other) to identify the prepared against the earthquake.
Please introduce me to resources that can help.
Thank you
How can advancements in material science and engineering contribute to the development of more sustainable and eco-friendly building materials, considering factors such as durability, energy efficiency, and recyclability in the construction industry?
Hello dears,
I would like to submit a new manuscript for construction and building materials journal. But authors must supply the names, addresses and institutional email addresses of 5 independent referees from outside their own country. Papers will be returned to the author if institutional email addresses of referees are not provided.
How I can solve this problem, I mean, What do they mean by that.
And are there any one could help me to be refereed?
What, in your opinion, are the methods, ways, legal solutions, new material and other technologies to reduce paper consumption, save wood and trees?
What, in your opinion, are the actions and projects that can contribute to forest conservation, to convert deforestation into afforestation, to protect the climate, biosphere and biodiversity of the planet's natural ecosystems, to reduce greenhouse gas emissions and counteract the ongoing process of global warming?
As we know, trees, forests, especially old, natural forests, primeval forests with old-growth forests without human interference, without the influence of civilization, are the refuge of the greatest resources of biodiversity of natural ecosystems. Besides, forests play a particularly important role in the issue of slowing down the human-induced global warming process, which is progressing faster and faster. Forests also play a very important role in mitigating weather and climate anomalies, maintaining a mild microclimate friendly to living organisms, keeping the soil and air moist, maintaining the high level of biodiversity and soil fertility created over thousands or millions of years, and so on.
Deforestation still dominates over afforestation in many regions of the world. Forests are still being cut down and burned to acquire new areas for agricultural development, the cultivation of crops, which is usually carried out in the form of unsustainable robbery. In addition, this practice is carried out mainly in the tropics and subtropics, where after logging, forests created new arable land is quickly subject to drought and the soil becomes barren. Restoring a forest that has functioned for thousands of years or more in a specific area on the depleted soil requires huge expenditures. In addition, vegetable crops are grown on these new agricultural areas, which are either transported thousands of kilometers to other countries, which generates high greenhouse gas emissions, or are not used for human food but for livestock feed, which also generates high emissions, as industrial livestock farming is a source of high emissions of the potent greenhouse gas methane. Therefore, with a view to protecting the climate, biosphere and biodiversity of the planet's natural ecosystems, to reduce greenhouse gas emissions and counteract the ongoing process of global warming.
Various examples of reducing paper consumption and saving forests are as follows:
In some countries, the scale of printing notebooks, notebooks, books, including school books, has been reduced and students as early as elementary school write at school on tablets or laptops rather than in paper notebooks. Green economic activities involving, for example, the production of furniture from recycled materials are also emerging.
Another example is the replacement of dirty energy based on burning firewood with renewable and emission-free sources of clean energy. Unfortunately, in some countries, in order to falsify statistics on the development of renewable energy at the behest of the government, central statistical institutions, ministries and government agencies dealing with climate and environmental issues also count firewood as a renewable energy source. Such absurdities unfortunately still exist in some countries.
Another example is the use of secondary raw materials of various origins in the construction industry instead of using wood, and especially instead of newly harvested wood from companies producing building materials based on fresh, new wood raw material from a sawmill.
As of 1.8.2023, paper receipts are not printed in France to save trees. You have to ask for a printed receipt if the customer needs one.
What other examples of reducing paper consumption and saving forests are as follows?
In view of the above, I address the following question to the esteemed community of scientists and researchers:
What, in your opinion, are the actions and undertakings that can contribute to forest conservation, to convert deforestation into afforestation, to protect the climate, biosphere and biodiversity of the planet's natural ecosystems, to reduce greenhouse gas emissions and counteract the ongoing process of global warming?
What do you think are the methods, ways, legal solutions, new material technologies and others to reduce paper consumption, save wood and trees?
How can we reduce paper consumption, save wood, trees and reduce forest deforestation, protect biodiversity and climate?

There are many parameters that make the built environment more sustainable. A cradle-to-cradle approach with the production processes of the building materials and the built environment and their design quality play a major role in its sustainability. With this question, it will be interesting to know if the state intervention in terms of development control rules helps in achieving sustainability in the built environment to reduce environmental impacts.

How can an energy independent home be built?
How can a zero-energy (energy-neutral) house be built?
How can a zero-emission and energy- and climate-neutral house be built?
What combination of energy efficient building technologies and renewable energy sources should be used to build a fully energy independent home?
What are the key priors for sustainable, environmentally friendly construction?
Various solutions are being used in the construction industry to reduce energy consumption and CO2 emissions into the atmosphere. New building materials are being used, as well as insulation materials for facades to reduce heat loss. Various renewable and emission-free energy sources are used (windmills, photovoltaic panels, others). Thermal (in winter) and/or cooling (during hot weather) energy-generating devices based on heat pumps, air conditioners, etc. are used.
What are currently known to be the most convenient, sustainable, energy-efficient and cost-effective combinations of applied energy-efficient building technologies and various, especially renewable/zero-emission energy sources in fully energy-independent houses?

Dear Gabriela,
Correct. A specific climatic, geographic and natural zone characterised by a specific weather aura and state of the environment is relevant in this respect. On the other hand, the available modern technologies included in sustainable construction are also among the relevant factors. In view of the above, both the natural climatic and natural environment factors and the available, modern technologies determine the possibilities for the development of sustainable, environmentally and climate-neutral construction.
Thank you very much,
Best regards,
Dariusz

I am working on earth-based material reinforced with cellulose fibre for building applications. The results of the thermal conductivity have been found between the range of 0.350 and 0.695 W/(m.K). However, I can found in the literature the standard range for thermal insulation material for building application. I will really appreciate your help.
I found two articles with options for quantification of amorphous C-S-H:
• Bergold, S. T., Goetz-Neunhoeffer, F., & Neubauer, J. (2013). Quantitative analysis of C–S–H in hydrating alite pastes by in-situ XRD. Cement and Concrete Research, 53, 119-126.
I would like to insert the article data (lattice parameter, space group and all the “hkl”, d and °2θ information for each reflection) as a model pseudo-structure, but I only found the option to insert the structure with lattice and space group parameters, as we do in PONKCS (Partial Or No Known Crystal Structure). The software also needs this reflection information, since I don't have C-S-H to run ... Is it possible to create a ".cif"?
• Suh, J. I., Yum, W. S., Jeong, Y., Park, H. G., & Oh, J. E. (2019). The cation-dependent effects of formate salt additives on the strength and microstructure of CaO-activated fly ash binders. Construction and Building Materials, 194, 92-101.
The authors used the XRD pattern of fully hydrated β-C2S as a reference pattern after the reflections of portlandite were removed. I managed to find the original article (Mohan, K. and Taylor, H.F.W. (1981). J. Am. Ceram. Soc. 64, 717), but I couldn't understand how they generated this pattern for consideration in the XRD software.
if i want to classify opc, ppc using there hyperspectral data and deeplearning how should i do it.
please tell name of any pretrained network that can help via transfer learining.
Insulation materials come from different sources. Each material has advantages and disadvantages that must be considered when selecting insulation for buildings. What would you recommend other than the commonly used materials?
please give any information about the Conference on Building Materials or Sustainable Materials
We are trying to choose between simultaneous DSC/TGA's from Neztsch (Jupiter F5) and Setaram (Labsys). They both offer very similar systems. Seteram does have an advantage in heat capacity where they can use a 3-dimensional cell, but I do not know if that will be relevant to us. If it makes a difference, we will be using it primarily for Gypsum and perhaps other building materials and/or paints and coatings.
Could someone provide an unbiased opinion if they have noticed differences in the instrument sensitivity, software, service, or some other area of Nezstch versus Setaram?
I need references articles that explain the drawings for the following materials, which illustrate the diagram between DR UV-Vis spectrums of the following materials blank sample as expressed in Kubleka-Munk function versus
the measured wavelength and the materials are ZnO, CuO, Fe2O3, and Co3O4.
Hi there :) I made a model in Sketch up with Open Studio plug in and Energy Plus. The model is a student dormitory (residential building) with 60 thermal zones. It has internal loads (people, equipment, lights etc), also all the building materials are added in the envelope (walls, roof, slabs, windows etc). The weather file is from Skopje (epw file). I am still working on the HVAC :)
I made a simulation in EP (finally with no severe errors :)..To see the results, I used xESO Viewer and there were only one graphic about the dew point outside temperature. The were no graphics for the other output:Variable data (the other graphics are just a straight line).
I am sending the idf.file of the model, eSO file results and screen shoots from the xESO graphics.
Could somebody please help me with this issue and explain about how to visualize the graphics in xESO Viewer. I don't know what l am doing wrong? Maybe I am missing some input commands?!
Any kind of answer will be highly appreciated!
Thank you very much in advance...
Looking forward to hearing from you,

According to the previous studies [1-3], an increase in the S/C ratio within the range of 0.5 to nearly 2.25 results in a gradual increase in the compressive/flexural strength while the S/C ratio higher than 2.25 can reduce the compressive/flexural strength of the cement mortar. My mix-design consists of general-purpose cement, silica fume, superplasticizer, viscosity modifying agent, and washed high purity silica sand with a maximum particle size of 600 µm and fineness modulus of 1.29. all the proportion including the water/cement =0.35 kept constant except the S/C which changed from 0.8 to 1.0 and 17% reduction observed in compressive strength.
Moreover, the addition of Sand resulted in a lower density and all the compressive and flexural strength were measured after 28 days of curing.
Can this phenomenon be explained by the fineness modulus (particle size distribution) and/or changes in the porosity of the mixes?
Why are concrete and red-brick buildings cyan in infrared false color (IRFC) images?
Most building materials are made of soil (e.g. red tile roofs or concrete), thus most urban areas have the spectral signature of a soil.
Nevertheless, in IRFC satellite images we usually see bright urban areas in Bright Cyan instead of Dark Brown/LightBrown to Orange or Whitish. why is that?
The most used fibers for ECC are PVA and PE, however, these fibers are very expensive. Are there other cheaper and greener materials that can be used as fiber in ECC?
They say the following can optimise the free MgO having the culprit periclase ,free lime(CaO, CaOH) which result in delayed solidification or setting and expansion and lead to surface cracks of roads if used for bitumen and land filling for laying roads, cracks in walls if used in aggrgates as building materials and bricks in walls.
1.acclerated steam injection process can accelerate ageing of LD slag along with
2.crushing to a size whereby you modify the elongation and flaking index to eliminate the needle like as well as porous micro structure
Then comes the P2O5 and sulphur which cause rust if used in reinforced structures which is to be controlled.
How can all this be done? Can i be given a reference to some papers which can combine all this knowledge to comprehend and get the conceptual clarity , so as to proceed with commercialising the LD slag available in abundance in my place

Sustainable Public Procurement compliance versus very scarce resources in government service delivery. A typical example would be a Durban community in need of 500 houses and the South African government do have money to build them. However, in order to comply with SPP the government must adopt and use "green houses" approach which is, in most cases uses very expensive building material. Therefore, the government must choose to build "normal" 500 houses OR build only "green" 70 houses. Will the community understand why must they get 70 houses while the money is enough to build 500 houses. Maybe, the well developed economies would survive the SPP compliance. What is your take on this ?

Its no new research that several studies have explored the use of alkali activated materials and geopolymer as a sustainable replacement to the conventional ordinary Portland cement. However, the sustainability of these materials is relative as it depends mainly on the availability of materials locally which eliminates the huge emission and cost associated with the transportation of both the raw materials and finished products. Therefore, the use of OPC might still be sustainable in some parts of the world compared to alkali activated materials and geopolymers
What is the main advantage of concrete over other building materials?
I want to separate the individual elements from a sample. Simply without chemicals. The sample includes:
Nepheline 34.5%. Alumina/Aluminium Oxide 14.4%. Anatase, syn TiO2 12.9% and Quarts. It is in powder form. As you can see there are some valuable elements, too good the use as building material.
I require the method to be scalable to industrial scale. Simple and cost effective.
One of the apparatus required for freeze and thaw test according to ASTM C666 is the dynamic testing apparatus. This apparatus is used to obtain the relative dynamic modulus of elasticity and durability factor of the concrete.
However, in case where the apparatus is not available, what other apparatus or parameter can be used ?
Few studies have used UPV as an alternative, but i'm still seeking for alternative methods.
Thanks
Let say our common building material for example bricks made of sand, clay and cement, so I want to know how much energy absorbed of bricks and how the retention time of the energy absorbed?
I am wondering if there is any literature review or any other types of information about the consumption of different materials, e.g. cement, concrete, and steel in the construction of different building types, i.e. residential and non-residential, especially in Australia. I also would like to know if there is any literature review about the embodied energy of the different materials, and the impacts of the consumption of the different materials on energy consumption and Co2 and GHG emission the building operation phases? As you know, building materials have somehow lots of things to do with building efficiency during the operation phases by affecting cooling, heating, ventilation, and even lightning, hence have lots of things to do with Co2 and GHG emission, and have an essential role to be considered in any mitigation action plans.
I used a frame structure to represent a continuous shell plate and this frame structure was calibrated with a physical model in order to have the same rigidity as the real one. However I was trying to identify how representative would if a change the thick of the frame elements to represent a shell plate.
Thank you in advance.
To the hardened cement paste, how much water it can absorb after drying at 80 degree for more than 1 week at the water to cement ratio 0.44?
1)We made building on Google sketchup
2)We then imported it on Trnsbuild where we defined all properties eg ventilation,infiltration,building material .
3)Now we want that trnsys calculate building cooling & heating load for whole year for us.
4)Moreover how trnsys come to know when our heating season start and when our cooling season start .
We are attaching the images of our simulation results.when we run simulation on clicking on heat load calculation,simulation run but we get nothing.
How weather conditions (air temperature, humidity, solar radiation, precipitation, etc) affect the construction materials (concrete, steel, wood)?
please give the details for experimental set up....
Hydrostatic forces act to push at walls that are either buried or bermed. Can superadobe withstand the lateral forces at work in a bermed building, or will it need more lateral support such as buttresses etc.
The aim is to follow the evolution of the attenuation coefficient vs. mortar age.
The experiments will be done using the Ultrasound Pulse Echo Method with P-waves and by Immersion testing (using imersion transducers)
Would be most interested in regulatory standards regarding both materials and skills, but also interested in wider regulation issues.
How can buildings materials efficiently be classified other than via Raman spectroscopy?
Earth is one of the oldest and most widely used building materials worldwide. Do you know of any reliable studies on the maximum density and bearing capacity of rammed earth (tapial) technique?
I am specially interested in informatinos about Peru.
Our group design fiber rolls rack. Safety that must be taken to when handle the fiber rolls?
There is currently increased focus on using timber as the primary building material for construction. Design firms are now creating feasibility studies for timber high-rise buildings.
Due to the specific structural requirements and wind loading/bracing, does timber limit the flexibility of design for buildings?
Is anybody aware of any resource that offers some advice/figures on measured vs. calculated building fabric U-Values?

I search for bibiliographic or other ( research studies, scientific papers to gather information about mechanical, thermal and physical properties of classic building and insulating materials. Any referencing hint would be helpful.
Where could I find data of production cost and energy consumption of building materials and raw materials extraction processing for building materials manufacture?
Currently there seem to be no standard that covers how to carry out an accelerated corrosion test for steel in a reinforced cementatious composite. However, several studies have explored different ways by passing electrical charges through concrete samples soaked in sodium chloride solution
What is the best way to have an accelerated quantitative assessment of corrosion of steel in concrete? Any suggestions, papers or standards if available will be greatly appreciated
if there is so then it may be good alternative material to electric Wires.
Non destructive tests equipment for concrete are quite expensive and not readily available. Is there any non destructive test that can be improvised or built with commonly available materials to determine the strength or/and permeability properties of concrete and other cementitious composites?
It is logical to assume development of seaweed as a biomaterial will allow it be used as building construction materials in the near future?
The use of supplementary cementitious materials (SCMs) is increasing rapidly as they can be used to partially or totally replace OPC in concrete.
The most common types of SCMs are fly ash, slag, metakaolin and silica fume. However, the supply of some of these SCMs will be limited in coming years.
What are the other types of emerging SCMs that can be used in concrete?
Engineered cementatious composites are high performance composite and are gaining huge research recently due to their enhanced ductility and durability.
What are the major ways to improve the sustainability of the ECC?
Due to the diversity of building materials, there are many equations for calculating the crack spacing and crack width of reinforced concrete members, in which some empirical parameters are used. These structural members are a combination of the following materials:
CONCRETE: normal concrete (NC), ultra-high performance concrete (UHPC), fibre-reinforced cocnrete (FRC), lightweight aggregate concrete (LAC), geopolymer concrete (GPC).
REINFORCEMENT: steel, fibre-reinforced polymer (carbon, aramid, basalt, glass), textile-reinforcement.
I would like to know whether there is a general formula for determining the crack spacing of reinforced concrete members? If not, could you give me the "best" equations of crack spacing according to your opinion and experience.
I am also very happy if you can share me literature regarding experimental results of crack spacing and crack width of reinforced concrete members.
Thank you,
