One of the solutions for overheating the interior in the summer without increasing energy consumption is the integration of phase change material (PCM) into interior plasters. However, adding PCM to plasters deteriorates their properties and thus their usability. The aim of this paper is to determine how the microencapsulated PCM affects the mechan...

The importance of green and sustainable materials in civil engineering is undeniable. Alongside modern practices that improve the properties of standard building materials, there are ways to revive forgotten techniques, including straw bale buildings. Straw bales are load-bearing structures, which are applied based on handed-down experience and lac...

Sustainable development in civil engineering is the clear and necessary goal of the current generation. There are many possibilities for reducing the use of depletable resources. One of them is to use renewable and recyclable materials on a larger scale in the construction industry. One possibility is the application of natural thermal insulators....

The paper deals with the research on the properties of secondary raw materials resulting from the recycling of used tyres and their potential utilization for the production of construction insulations. Evaluation of the possibilities of utilization and a complex analysis has been executed on the basis of the defined basic physical, thermal-insulati...

Ignitability is one of the parameters that characterize the behaviour of building materials on flame action. The Ignitability Small Attack Flame fire test is used for the classification of building products by their reaction to fire. On the basis of the Ignitability fire test it can be determined that the tested material will be classified into the...

This paper describes the results of a scientific project focused on determining of the Airborne Sound Insulation of a peripheral non-load bearing wall made of straw bales expressed by Weighted Sound Reduction Index. Weighted Sound Reduction Index was determined by measuring in the certified acoustic laboratory at the Faculty of Mechanical Engineeri...

One of the methods used for determining of the thermal conductivity coefficient value of building materials is the Calibrated and Guarded Hot Box method. This method is based on the principle of measuring the heat flux density that passes through the test specimen at a temperature difference between warm and cool parts of the measuring box. For mea...

To full utilization of crushed straw in civil engineering industry is necessary to know its technical parameters. During previous projects on VŠB – TUO, Faculty of Civil Engineering have found parameters like settlement, thermal conductivity or airborne sound insulation. The research on these parameters have had favorable results, therefore the res...

This contribution deals with the fire resistance of wood construction segments with the infill insulation based on natural materials. An integral assessment of new and existing structures is to verify their resilience in emergency situations. One of the most common emergencies is fire. If required to determine the fire resistance of structural mech...

Old structural timber has its aesthetic and technical value and there are many ways how to use old wood in current civil engineering. It is used for reconstruction of historic buildings or we can use it as design building material for modern and architecturally interesting buildings. Old timber has beautiful color shades which are inimitable for ne...

This article is focused on an experimental measurement of settlement of blown insulation from crushed straw. Straw has appeared like building material in recent years. It is ecological and cheap building material which is required for sustainable construction. Straw is usually used in form of bales. These are generally used like thermal insulation...

Paper presents results of measuring of airtightness and acoustic properties of clay house. This clay house was built as a "SuperAdobe house" from the bags filled with clay. Construction of the clay house is a cupola. Objective of the measurement was to evaluate the quality of peripheral construction in terms of airtightness. We also wanted to verif...

Construction has recently become greener and returns to the materials that used by our ancestors. Recycled paper is considered as ecological material. Cellulose insulation is made from it has been used for several years. People do not believe in this blown insulation mainly due to the settlement and the creation of thermal bridges in the least desi...

With regard to the current European trends in civil engineering and sustainability are still explored new building materials. In this case it is ideal to use natural materials such as straw. Its use as a building material is both ecological and economical. Excellent thermal insulation properties of straw have been known for centuries but the aim of...

Straw bales can be used as a relatively cheap and ecological building material for buildings. Design of straw buildings is currently based on empirical knowledge although it would be very helpful to have more information about material properties for designing and realization of straw bales houses. Article discuses load - deformation behavior of st...
