recycled concrete coarse aggregate

基本解释

The influence of recycled coarse aggregate replacement rate on properties of concrete with the same slump is discussed in the paper.
系统研究了坍落度相同的情况下再生粗骨料取代率对混凝土基本性能的影响。
The results show that the compressive strength and elastic modulus of recycled coarse aggregate concrete are lower compared with conventional concrete.
结果表明：相对于普通混凝土，随着再生粗骨料取代率的增加，再生粗骨料混凝土具有强度和弹性模量降低等特点；
On the physical properties, many deferent ingredients of recycled concrete are tried by adjusting concrete mixture ratio including the recycled coarse aggregate, FDN and fly ash.
在再生混凝土基本性能方面：通过采用不同的水灰比、不同的再生骨料的取代率以及不同的减水剂掺进量，配制再生混凝土。
