以不同比例再生细骨料取代天然砂,研究了再生细骨料掺量对湿拌砂浆及掺石粉湿拌砂浆基本性能的影响。结果表明:再生细骨料对湿拌砂浆性能影响较为显著,石粉取代部分细骨料对再生细骨料湿拌砂浆性能具有改善作用。综合分析,再生细骨料掺量为30%、石粉掺量为10%,可制备性能较优的湿拌砂浆。 In order to replace the natural sand with different proportions of regenerated fine aggregate, the effects of the recycled fine aggregate content on the basic properties of wet mixed mortar and wet mixed mortar with limestone were studied. The results show that the effect of recycled fine aggregate on wet mortar is more significant. The replacement of some fine aggregate by stone powder can improve the wet mortar properties of recycled fine aggregate. Comprehensive analysis, the recycled fine aggregate content of 30%, stone powder content of 10%, can be prepared better performance of wet mix mortar.
