Waste-rubberized ceramsite concrete is an improvised building material that is suitable for lightweight wall panels, which can significantly reduce the bulk density of buildings. In this study, the effects of different water–cement ratios on the mechanical properties, water absorption, ultrasonic velocity, and sulfate corrosion resistance of waste-rubberized ceramsite concrete were investigated, and scanning electron microscopy (SEM) was used to study the microscopic interface. The test results show that the water–cement ratio of 0.45 is optimal. The compressive strength, water absorption rate, and ultrasonic velocity of the specimen first increased and then decreased as the water–cement ratio increased. The sulfate corrosion resistance of specimens with a high water–cement ratio is weaker than that of specimens with a low water–cement ratio. It is of great significance to explore the optimal water–cement ratio of the waste-rubberized ceramsite concrete for further research, and it has important production guidance significance for commercial applications.

废橡胶陶粒混凝土是一种适用于轻质墙板的简易建筑材料，可显着降低建筑物的容重。【摘要】：研究了不同水灰比对废橡胶陶粒混凝土力学性能、吸水率、超声速度和抗硫酸盐腐蚀性能的影响,并采用扫描电子显微镜(SEM)对微观界面进行了研究。 . 试验结果表明，0.45的水灰比最佳。随着水灰比的增加，试件的抗压强度、吸水率和超声速度先增大后减小。高水灰比试件的抗硫酸盐腐蚀能力弱于低水灰比试件。
