This writing evaluates and contrasts the performance of various deep learning models in predicting the tensile strength of self-compacting concrete incorporating recycled aggregates. Experimental data sourced from existing literature were used to create test, training, and validation sets. A range of artificial intelligence models and optimization...

The aim is to predict the compressive strength of self-compacting concrete with recycled aggregates by using machine learning methods. Various ensemble methods and generalized additive models were applied to a sample of 515 research articles divided into training, validation and testing. Compressive strength was considered as output variable and SC...

Concern for the perpetuation of stone monuments is deeply ingrained in humans; however, despite the attempts made in this field, there is still a great deal of effort needed to bring about advancements in the conservation of ornamental stone. Erosive agents, such as rain, extreme temperatures, and chemical and biological agents, threaten our stone...

Over the years of teaching the subject of Technical Drawing, we teachers have verified that many students have significants problems when it is time to learn the topic of mechanical assemblies, in terms of understanding how they work, the position of their parts and the relative displacement between them. These issues are essential for a better sta...

A main global challenge is finding an alternative material for cement, which is a major source of pollution to the environment because it emits greenhouse gases. Investigators play a significant role in global waste disposal by developing appropriate methods for its effective utilization. Geopolymers are one of the best options for reusing all indu...

University education in times of COVID-19 was forced to seek alternative teaching/learning methods to the traditional ones, having to abruptly migrate to the online modality, changes that have repercussions on student satisfaction. That is why this study aims to compare the level of student satisfaction in face-to-face and “forced” online modalitie...

El ABP es un método pedagógico que favorece el aprendizaje significativo, y en el que los alumnos trabajan autónomamente en la realización de un proyecto que plantea la resolución de problemas, reales y motivadores, abordando temáticas del currículo educativo. Una de sus características es la ausencia del marco tradicional de aprendizaje en el aula...

The objective of this paper is to analyse the influence of design parameters on the fresh and mechanical properties in the manufacture of self-compacting concrete with recycled fine and coarse aggregates. Design parameters such as water-cement ratio, water/paste ratio, total aggregate to cement ratio, fine aggregate to coarse aggregate ratio, water...

Most concrete studies are concentrated on mechanical properties especially strength properties either directly or indirectly (fresh and durability properties). Hence, the ratio of split tensile strength to compressive strength plays a vital role in defining the concrete properties. In this review, the impact of design parameters on the strength rat...

The purpose of Graphic Design is to transfer information about design into reality and concerns the analysis, design and representation of mechanical components and assemblies. For the correct rendering of mechanical components, this discipline requires a command of, and the ability to, manage techniques and systems for graphical representation and...

One of the growing demands in concrete manufacture is the availability of natural fine aggregates, which account for 35% to 45% of the total concrete. An alternative method of disposal of fine recycled concrete aggregates (FRCA) generated from demolition and construction waste (C&DW) is their usage in mortar and the development of recycled mortar....

This article presents an overview of the bibliographic picture of the design parameter’s influence on the mix proportion of self-compacting concrete with recycled aggregate. Design parameters like water-cement ratio, water to paste ratio, and percentage of superplasticizers are considered in this review. Standardization and recent research on the u...

La Fabricación de un modelo de un terreno no es algo muy corriente, pero, a veces, aporta una serie de ventajas importantes que hacen aconsejable afrontar su realización, sobre todo si se utiliza una tecnología como el Prototipado Rápido, precisa, rápida y sin un elevado coste económico. El OBJETIVO del presente trabajo es describir el proceso de c...
