摘要
在粗骨料中掺入部分再生骨料,其再生粗骨料取代率依次为0、20%、25%、30%、50%、70%和100%。然后根据这7种骨料配制了7组混凝土,对混凝土进行了工作性能和力学性能检测。通过对7组混凝土性能分析得出:再生粗骨料的掺入对混凝土工作性能和力学性能影响较小,未观察到混凝土工作性能和力学性出现明显不利变化。
When coarse aggregate is mixed with part of recycled aggregate,the replacement rate of recycled coarse aggregate is 0,20%,25%,30%,50%,70%and 100%.Then 7 groups of concrete were prepared according to these 7 kinds of aggregates,and the working performance and mechanical properties of the concrete were tested.Through analyzing the performance of 7 groups of concrete,it is concluded that the mixing of recycled coarse aggregate has little effect on the working performance and mechanical properties of concrete,and no obvious adverse changes in the working performance and mechanical properties of concrete have been observed.
