Finally, some basic strength indexes of C20 ~ C40 recycled concrete with 100% RCA are proposed.

最后，针对再生粗集料取代率为100%的C20 ~ C40再生混凝土主要强度指标的取值提出了建议。

In the test, the strength grade of concrete is C20 and C60, and the cementitious system contains 10%, 20%, 30% and 40% of fly ash in accord with weight.

实验中应用的混凝土的强度等级分别为C20和C60，其中粉煤灰的掺量(胶凝材料的质量分数)分别为未掺、10%、20%、30%、40%。
