建筑垃圾再生微粉对生土材料性能的影响

Effect of Construction Waste Recycled Fine Powder on Properties of Raw Soil Materials

针对于掺加再生微粉的生土材料性能进行分析,分别探究了其抗压、耐水浸泡、吸放湿及干湿循环性能。研究结果表明:(1)当掺加再生微粉、水泥处理生土材料时,对于常温环境下仅当I级、II级RBP掺量分别在6%~14%、10%时能够起到提升强度的作用。(2)当掺加再生微粉、水泥处理生土材料时,对于常温环境下均会提升材料的耐水浸泡、吸放湿性能。

The properties of soil materials mixed with recycled micro powder were analyzed, and the properties of pressure resistance, water immersion resistance, moisture absorption and release and dry and wet cycle were explored respectively. The results show that:(1) when the recycled powder and cement are added,the strength can be improved only when the content of grade I and grade II RBP is 6% ~14% and 10%,respectively, at room temperature.(2) When adding reclaimed powder and cement treated soil materials, the water immersion resistance and moisture absorption and release performance of the materials will be improved under normal temperature environment.
