Thermal Performance Improvement of Foam Mortar with Calcined Marl Blended Cement

The construction sector has a very high share in solving the energy demand of the world and global warming problems. Therefore, it had to increase studies on building materials-based heat storage and thermal insulation. Foam concrete is one of them, but its thermal and mechanical properties need to be improved. So, in this study, calcined marl was used as a replacement material to evaluate its thermal performance in the production of foam mortars. The aims of this study are to determine the physical, mechanical, and thermal properties of foam mortars produced with blended cements containing calcined marl at 0, 10, 30, and 50% ratios and to obtain novel and optimum design data for the foam concrete market. In conclusion, the optimum calcined marl replacement ratio is up to 30% in terms of both thermal performance and mechanical properties of foam mortars. Due to calcined marl, this study presents a foam mortar design with economic and low-carbon. And, thanks to the mixed designs of foam mortars prepared with blended cement containing novel calcined marl additive, it is observed that they improve the thermal insulation and heat storage ability of foam mortars and provide sufficient strength.
