recycled coarse aggregate concrete

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；
Orthogonal experiment results show that recycled coarse aggregate quantity is the main factor that influences recycled concrete compression strength and slump.
正交試騐表明，再生粗骨料的摻量是影響再生混凝土強度和坍落度的主要因素；
