摘要
通过7d抗压强度试验、28d干缩性能、28d劈裂强度试验研究建筑垃圾掺量对水泥稳定建筑垃圾路用性能的影响。试验结果表明:随着建筑垃圾掺量的增加,水泥稳定建筑垃圾的7d抗压强度、28d劈裂强度降低,28d干缩系数增大。建筑垃圾掺量为100%时,再生水泥稳定建筑垃圾的7d抗压强度比普通水稳碎石降低了23%,28d劈裂强度降低了31%,28d干缩系数增大了16%。
The influence of the amount of construction waste on the road performance of cement stabilized construction waste was studied through 7d compressive strength test,28d drying shrinkage test and 28d splitting strength test. The results show that with the increase of construction waste content,the 7d compressive strength and 28d splitting strength of cement stabilized construction waste decrease,and the 28d drying shrinkage coefficient increases. When the content of construction waste is 100%,the 7d compressive strength of recycled cement stabilized construction waste decreases by 23%,the 28d splitting strength decreases by 31%,and the 28d drying shrinkage coefficient increases by 16%.
