摘　　要：地铁淤沙是在地铁开挖过程中产生的一种砂性原料,介绍了杭州钱塘江两岸地铁开挖过程中产生的淤沙情况,对地铁淤沙在蒸压加气混凝土中的应用进行研究,分析了地铁淤沙的基本性能,对地铁淤沙生产蒸压加气混凝土产品试验研究。结果表明,地铁淤沙掺量为30%、50%和100%时生产的蒸压加气混凝土产品性能均能够满足B06A5.0要求,验证了地铁淤沙在蒸压加气混凝土中应用的可行性。The subway silt is a kind of sandy raw material produced in the process of subway excavation.This paper introduces the silt produced in the process of subway excavation on both banks of Qiantang River in Hangzhou,studies the application of subway silt in autoclaved aerated concrete preparation,analyzes the basic properties of subway silt,and makes an experimental study on the production of autoclaved aerated concrete products with subway silt.The results show that the properties of autoclaved aerated concrete produced when the subway silt content is 30%,50%and 100%can meet the requirements of B06A5.0,which verifies the feasibility of the application of subway silt in autoclaved aerated concrete.
