摘　　要：利用废弃混凝土生产再生细骨料,然后以不同掺量取代人工砂生产普通砂浆,就再生细骨料掺量对普通砂浆性能包括用水量、保水性、凝结时间、拉伸粘结强度和抗压强度的影响进行了相关研究。试验结果表明:一定量的再生细骨料取代人工砂生产普通砂浆是可行的,可以满足相关标准、规范、工程的要求。Waste concrete is used to produce recycled fine aggregate,and then the mixed amount of artificial sand is used to replace the ordinary mortar,it is studied on the effect of recycled fine aggregate content on the properties including water consumption, water retention, setting time, tensile bond strength and compression strength of the ordinary mortar. The results showed that it is feasible to replace artificial sand with a certain amount of recycled fine aggregate,and it can meet the relevant standards,specifications,engineering requirements.
