Abstract

Foam concrete has attracted attention worldwide because of its light weight and enhanced insulating properties as a building material. Pore features in foam concrete play an important role in affecting its compressive strength and insulation properties. Therefore, quantitative description of relationships between pore features heat conductivity and compressive strength is the main aims of this thesis. To accomplish the aims, theoretical method is employed to deduce the heat conductivity, and experimental method is used to justify its compressive. Further, Matlab and Python program are programmed to depict the random pore distribution, and then finite element method is employed to calculate its compressive based on the pore distribution.
