In order to study the performance of composite heat insulation concrete for mine, mixture ratio design of 18 group samples were designed based on the orthogonal design theory, then its strength and thermal conductivity were test. The integrated balance method is used to analyze the test data, and established the model of thermal conductivity theory. Through comparing with the measured thermal conductivity, the effect factors on thermal conductivity and compressive strength were analyzeddoi:10.12783/dtetr/tmcm2017/12674 fatcat:kmstyiz7tjeznngjek37rw2mta
