Waste Mortars, Thermal Performance, Energy Efficiency, ThicknessAbstract
In this work, industrial waste such as steel slag, friable quartzite, and iron ore tailings are being investigated as substitutes for river sand. These waste materials have shown promising mechanical and physical performance, making them viable options for building construction while reducing the environmental impact of sand extraction. Additionally, energy efficiency plays a crucial role in reducing energy consumption in the construction sector. Therefore, this study examined the impact of varying the thickness of sustainable mortar coatings on the thermal performance of a building. The conducted energy simulations demonstrated that adjusting the thickness can enhance thermal performance, resulting in energy savings. Beyond the energy benefits, the utilization of these waste materials also contributes to reducing socio-environmental impacts. In conclusion, the proper adoption of sustainable mortars can enhance the thermal performance of buildings in Brazil, aligning with the sustainability goals of the construction industry.
