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.
系統研究了坍落度相同的情況下再生粗骨料取代率對混凝土基本性能的影響。
The results show that the compressive strength and elastic modulus of recycled coarse aggregate concrete are lower compared with conventional concrete.
結果表明：相對於普通混凝土，隨著再生粗骨料取代率的增加，再生粗骨料混凝土具有強度和彈性模量降低等特點；
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麪：通過採用不同的水灰比、不同的再生骨料的取代率以及不同的減水劑摻進量，配制再生混凝土。
