The Optimization of Performance the New Type of Insulation Wall Materials Based on Waste Foam Glasses

Abstract

A new type of insulation wall is developed based on waste foam glasses. Performance tests small particle size (1~10mm) foam glass block with mass ratio of 30%~50% shows that the coefficient of thermal conductivity and compressive strength of insulation block are blow 0.2w/(m.K) and above 3.10MPa, respectively. This indicates a well insulation performance and mechanical property however the density and strength are not good enough. If the large particle size (20~65mm) are used with the mass ratio of 50~80%, the density can be lower than 400kg/m3 and the coefficient of thermal conductivity and compressive strength of insulation block are 0.2w/(m.K) and 0.5MPa, respectively. This indicates a lighter weight and better insulation performance. If the 44.7% construction waste are added to the insulation walls, the compressive strength can be improved more than 90% and meet the requirement of bearing walls.
