Numerical Analysis on Hollow EPSRC Block and its Thermal Insulation Wall

Abstract

A new building material named expanded polystyrene recycled concrete (EPSRC) has been experimental studied not long ago by authors in this paper. Now, numerical analysis was further carried out on hollow EPSRC block and its thermal insulation wall based on thermodynamic principles. The results showed that the average thermal resistance of E45 and E60 EPSRC blocks are 0.616 and 0.823 (m2·K)/W, and the average heat transfer coefficient of E45 and E60 EPCRC masonry wall are 1.473 and 1.280 W/(m2·k). Therefore, the EPSRC blocks can be widely applied to the non load-bearing lightweight insulation masonry by suitable design.
