Study on the Thermal Conductivity Model of Cement-Based Materials by a New Test Method

Abstract:

Thermal conductivity prediction models of cement-based materials are inconsistent. In order to get the correct model, parallel hot wire method is used to measure the thermal conductivity of aggregate, cement paste, mortar and cement-based materials. Theoretical analysis values and experimental values of thermal conductivity of cement-based materials are compared to get the correct series-parallel model of the material. Through further research, the test results that the influence of aggregate location and aggregate size on the thermal conductivity of cement-based materials can be ignored in the case of the same aggregate content.
