摘　　要：对矿渣部分取代水泥和使用再生粗骨料取代天然粗骨料两个方面综合对混凝土力学性能的影响进行了研究。结果表明:再生骨料混凝土中掺入矿渣,可以减弱在再生骨料对混凝土强度的不利影响,能够较为稳定的生产出C40再生混凝土;矿渣的掺量对再生骨料混凝土强度影响显著,矿渣掺量为50%时,混凝土力学性能最好;试验数据同时显示掺较小粒径再生骨料的混凝土比掺粒径较大再生骨料的混凝土的土力学性能好。The mechancical behavior of concrete of the concrete containing slag and recycled concrete aggregate were studied.The results showed that slag was particularly beneficial for concrete with recycled aggregate and reduces strength losses.That is very beneficial to make stable performance recycled concrete of C40.In addition, slag content had an major influence on the strength of recyeled aggregate concrete.It was deter- mined that the mixes containing 50% salg gave the best overall performance.Values proved that used the small recycled coarse concrete aggregates making recycled concrete is more favorable than used ~e large size.
