摘　　要：研究了硅烷乳液、硅烷/聚硅氧烷混合物、烷基改性聚硅氧烷等3种不同类型有机硅憎水剂对免蒸压粉煤灰加气混凝土吸水率、抗压强度、浇注稳定性、密度等的影响。添加有机硅憎水剂,可明显降低加气混凝土的吸水率;不同类型的有机硅对加气混凝土强度和浇注稳定性的影响各不相同,而对密度则无明显影响。The influences of different kinds of silicone water repellents （Silane emulsion,silane/polysiloxane mixture,alkyl-modifled polysiloxane） on non-autoclaved aerated concrete were researched, including water absorption,compressive strength,casting stability and unit weight. The water absorption of non-autoclaved aerated concrete can be reduced by adding silicone water repellents：the influences on compressive strength and casting stability are various with different kinds of silicone water repellents,while no obviously influence on unit weight.
