摘要
制备不同密度钢纤维轻骨料试样,测试其抗压强度及单轴拉伸性能,分析力学性能。结果表明:加入聚合物乳液改性后,可提升载荷下钢纤维轻骨料试样裂缝约束能力,增强承载性;添加钢纤维的轻骨料密度为1695 kg/m^(3)时,墙体降温隔热效果最好,韧性好,抗拉强度高。
Steel fibers light aggregate specimens with different densities were prepared,and the compressive strength and uniaxial tensile properties were tested to investigate the mechanical properties. The results show that the addition of polymer emulsion can enhance the restraint capacity of crack and enhance the bearing capacity of steel fiber lightweight aggregate under loading. When the density of lightweight aggregate added steel fiber is 1 695 kg/m^(3),the wall has the best cooling and heat insulation effect,good toughness and high tensile strength.
