This article describes a thorough investigation of the physical and thermal properties of lignin based polyurethane building materials. The materials were created with lignin polyol and isocyanate. Factors investigated included compressive strength, thermal conductivity, burning behaviour, and morphology. The authors determined that compressive strength depended on the amount of lignin in the material, the sample containing 30% lignin had the highest strength. The thermal conductivity of the sample with the highest ...
This article studied the thermal conductivity of samples of autoclaved aerated concrete with various densities at high temperatures in order to produce data that could be used to assess and predict the performance of buildings during a fire. The mica sensor was employed for high temperature measurements. The values obtained by the authors experimentally were then compared against the reference values provided by national and international standards for high temperature ...
The work presented in this thesis was performed in order to generate knowledge of heat storage in building structures. The goal was to discover what material could most effectively reduce peak powers required by buildings by keeping buildings warm or cool without the necessity of using power....
The thermal properties of engineered bamboo products were investigated as these products show promise for use as building materials due to their improved mechanical properties over traditional timber building materials. It was determined that the thermal conductivity was lower for the bamboo materials than for timber, which indicates that these materials could potentially be used in the construction of energy efficient buildings....
A porous matrix was prepared using low-density sawdust and a metakaolin-based geopolymer paste. The matrix was prepared in order to evaluate its performance as a thermally insulating building envelope. The matrices that had approximately 4 MPa of bi-axial four points flexural strength were prepared in a ratio of geopolymer paste:sawdust of between 1:1 and 1:1.5, and the thermal conductivity of these matrices was between 0.2-0.3 W/m·K....
