摘要

粘土砖因其可持续性和成本效益被广泛应用于建筑中。然而,高密度和导热性等挑战阻碍了它们在节能建筑中的广泛应用。本研究探讨了膨胀添加剂和不同烧成温度(1000-1150℃)对轻质粘土砖物理力学性能的影响。制备了6组样品,膨胀剂添加比例为0 ~ 4%。关键性能包括单位体积重量、吸水率、孔隙率、抗压强度和导热性。结果表明,最佳工艺条件为添加3.5%的膨胀剂,烧制温度为1150℃,得到的材料单位重量为712 kg/m³,导热系数为0.1795 W/mK,抗压强度为7.05 MPa。这些发现证明了化学改性轻质砖在可持续节能建筑中的潜力。

Development of lightweight and thermally efficient clay bricks using expansion additives: effects of firing temperature and additive ratios on physicomechanical properties

Clay bricks are widely used in construction due to their sustainability and cost-effectiveness. However, challenges such as high density and thermal conductivity hinder their broader application in energy-efficient buildings. This study investigates the effects of an expansion additive and varying firing temperatures (1000–1150 °C) on the physicomechanical properties of lightweight clay bricks. Six sample groups were prepared, incorporating expansion additive ratios from 0 to 4%. Key properties, including unit volume weight, water absorption, porosity, compressive strength, and thermal conductivity, were evaluated. Results identified the optimal conditions as 3.5% expansion additive and a firing temperature of 1150 °C, yielding a unit weight of 712 kg/m³, thermal conductivity of 0.1795 W/mK, and compressive strength of 7.05 MPa. These findings demonstrate the potential of chemically modified lightweight bricks for sustainable, energy-efficient construction.
