| 摘 要： | 水泥混凝土道路改建时形成的废弃混凝土块的有效利用是一个亟待解决的问题。文章采用河北省国道G205秦皇岛段的废弃混凝土块,破碎后进行筛分,并对筛分后的集料进行磨耗试验、压碎试验、吸水率试验,将其与规范中天然集料的性能进行对比试验,得出旧水泥混凝土再生骨料的性能优于天然集料。

| Abstract: | How to effectively use the abandoned concrete produced during the cement concrete road improvement is an urgent task.The Author took the abandoned concrete block from Qinhuangdao section of Hebei provincial highway G205,crushed and screened it;then conducted abrasion test,crushing test,and water-absorbing capacity test on the screened aggregate.By comparing the test results with the performance of natural aggregate as specified in the Specification,it is concluded that the performance of recycled aggregate of existing cement concrete is superior to that of natural aggregate. |
