Thermal Insulation Test of RCCW with Inner Insulating Layer
To improve the durability of external thermal insulation plate on walls, the new reinforced concrete composite wall(RCCW) with inner insulating layer of polystyrene panel was developed. The paper introduces the thermal insulation tests of the RCCWs by the protection chest method, and studies the method for eliminating the effect of heat-bridge on the test results of conduct heat coefficient of the RCCW. The results show that the test value of conduct heat coefficient of the RCCW was obviously affected by the heat-bridge in specimen caused by the connected concrete such as support and concrete cover around the polystyrene panel, the practical value can be obtained by mean of taking off the percent of heat-bridge effect.
