摘 要:通过掺入不同含量的乳化沥青,对水泥混凝土的物理性能、力学性能和耐水性能进行相关试验研究,获得乳化沥青掺量对表观密度、抗压强度、抗折强度、折压比、应力-应变关系和耐水性等性能的影响规律。试验结果表明,乳化沥青的掺入降低了混凝土的力学性能,但折压比有所增长,弹性模量降低,材料的变形性能增强,同时耐水性有所提高。
Abstract: Through adding different content of emulsified asphalt, the physical properties, mechanical properties and water resistance of cement concrete were studied, the impacts for bulk density, cube compressive strength, flexural strength ratio of bending-compression strength, stress-strain relation and water resistance were found. Test result show that the addition of emulsified asphalt can reduce the mechanical properties and elastic modulus of cement concrete, but improve the ratio of bending-compression strength which proves deformation performance has been improved, meanwhile, the water resistance also improved.
