摘要
目前废弃的混凝土逐渐增多,一次同等级再生混凝土的研究已经处于一个比较成熟的阶段,然而对于再生粗骨料的循环利用研究没有更大的进展。为了合理利用好再生混凝土,可以将高等级的混凝土粉碎以后制成低等级的混凝土,实现再生粗骨料的多次循环利用。研究C30、C40、C50、C60不同强度等级分别循环为一次再生C30混凝土和二次再生C30混凝土的物理性能和力学性能,探讨循环再生混凝土在实际工程中的应用价值。
At present, the waste concrete is gradually increasing,the study of once cycled concrete is in a mature stage, but the study of the cycled coarse aggregate has not much progress. The grade waste concrete after being broken is made the low-level concrete for making good use of the cycled concrete,it makes cycled coarse aggregate cycle many times. The mechanical properties and physical properties of once cycled C30 concrete and twice cycled C30 concrete that are producted by C30 concrete,C40 concrete,C50 concrete and C60 concrete are studied. The value of the cycled con- crete is discussed in actual engineering.
