Thermal conductivity based mix design of cementitious materials
MetadataVis full innførsel
While cement-based materials are the most consumed materials in the construction industry, low or high thermal conductivity may be desirable for these materials depending on the application purposes such as embedded floor heating systems, building envelope or using as structural elements. The procedure of presenting prediction models for thermal conductivity of cementitious composites by considering different variables such as constituent materials, porosity and moisture content is described in this paper. The prediction model can be used for thermal conductivity based mix design of cementitious materials. Based on the desired accuracy, two methods for predicting the thermal conductivity are presented.
