One of the solutions for overheating interior in summer without increasing energy consumption is integration phase change material (PCM) into plasters. However, adding PCM to plasters deteriorates their properties and thus usability. The aim this paper determine how microencapsulated affects mechanical, thermal, fire much can be added plaster. Two sets samples were prepared: set S, part aggregate was replaced by PCM; R, only added. bulk density, flexural strength, compressive tensile...

This article is focused on the investigation of mechanical and thermal properties composite material that could be used for production plaster or plasterboards. made gypsum reinforcing natural fibers. The verifies whether this reinforcement can improve investigated compared to conventional plasters plasterboards pure gypsum. From material, high-strength then produced, which meet higher demands users than For their production, waste materials would efficiently. As part development new...

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 very helpful to have more information about properties designing realization houses. Article discuses load - deformation behavior in laboratory conditions evaluate the modulus elasticity local bales. Deformation characteristics useful design

Sustainable development in civil engineering is the clear and necessary goal of current generation. There are many possibilities for reducing use depletable resources. One them to renewable recyclable materials on a larger scale construction industry. possibility application natural thermal insulators. A typical example crushed straw, which generated as agricultural waste Czech Republic. Due its small dimensions good insulation parameters, this material can also be used blown insulation. The...

Paper presents results of measuring airtightness and acoustic properties clay house. This house was built as a "SuperAdobe house" from the bags filled with clay. Construction is cupola. Objective measurement to evaluate quality peripheral construction in terms airtightness. We also wanted verify parameters earthen structures determine value airborne sound insulation.

Abstract This paper describes the results of a scientific project focused on determining Airborne Sound Insulation peripheral non-load bearing wall made straw bales expressed by Weighted Reduction Index. Index was determined measuring in certified acoustic laboratory at Faculty Mechanical Engineering Brno University Technology. The measured structure modified combinations with various materials, so include wide range possible compositions wall. key modification application plaster both sides...

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

To full utilization of crushed straw in civil engineering industry is necessary to know its technical parameters. During previous projects on VŠB – TUO, Faculty Civil Engineering have found parameters like settlement, thermal conductivity or airborne sound insulation. The research these had favorable results, therefore the going and other characteristics are finding out. These days team deals with determination important fire straw. Fire play substantial character by building materials...

The importance of green and sustainable materials in civil engineering is undeniable. Alongside modern practices that improve the properties standard building materials, there are ways to revive forgotten techniques, including straw bale buildings. Straw bales load-bearing structures, which applied based on handed-down experience lack approaches testing, design, application. Therefore, a goal ahead describe every aspect process technical detail. objective this paper highlight practical ideas...

Ignitability is one of the parameters that characterize behaviour building materials on flame action. The Small Attack Flame fire test used for classification products by their reaction to fire. On basis it can be determined tested material will classified into class E precede Single Burning Item test, D, C, B , A2. results were carried out as part research properties gypsum composite with natural fiber reinforcement. As series ignitability tests two types out. first type was a reinforced...

Construction has recently become greener and returns to the materials that used by our ancestors. Recycled paper is considered as ecological material. Cellulose insulation made from it been for several years. People do not believe in this blown mainly due settlement creation of thermal bridges least desirable areas structure. This presents a description new test filling insulators which should clearly define issues settlement.

This article is focused on an experimental measurement of settlement blown insulation from crushed straw. Straw has appeared like building material in recent years. It ecological and cheap which required for sustainable construction. usually used form bales. These are generally thermal filling the supporting structure. An alternative to straw bales can be Crushed not industry currently. Its insulating properties structure appropriate use it or loose insulation. The was necessary verify...

The paper deals with the research on properties of secondary raw materials resulting from recycling used tyres and their potential utilization for production construction insulations. Evaluation possibilities a complex analysis has been executed basis defined basic physical, thermal-insulating fire textile fibres examined. results material examined indicate possible exploitation this environmentally-friendly objects. Thermal insulating parameters have determined by value thermal conductivity...

One of the methods used for determining thermal conductivity coefficient value building materials is Calibrated and Guarded Hot Box method. This method based on principle measuring heat flux density that passes through test specimen at a temperature difference between warm cool parts box. For Faculty Civil Engineering VŠB-TUO Cool Box. Measuring in uses same as creating during measurements not heat, but cold. Measurement by very complex terms measurement accuracy. That resulting values...
