Abstract

In north China, exterior insulation technology is adopted, brings a series of problems such as the lives of outer insulation material and building are different. A new composite insulation block has been put forward to solve these problems. The compressive strength and heat transfer coefficient of normal concrete composite insulation block (NC-190) was analyzed by ANSYS. Its simulation error is less than 10%. It can reflect the real working state. With this method, we forecast the compressive strength and heat transfer coefficient of recycled concrete composite insulation block (RC-190) with 100% recycled aggregate replacement ration. Its compressive strength 5.54MPa meets the non-load-bearing blocks’ strength requirements according to “Technical Specification for Concrete Small-Sized Hollow Block Masonry Buildings”. Its heat transfer coefficient 0.585W/(m2•k) meets the thermal insulation requirements of external wall in Yanji City (shape coefficient less than 0.3) according to “The Civil Building Energy-Saving Design Standard”.
