主要研究了水胶比、发泡剂稀释倍率、增稠剂种类和掺量、增强纤维种类和掺量等对泡沫混凝土性能的影响，以期找到改善泡沫混凝土性能的措施．研究结果表明：在水胶比为0．3及发泡剂稀释倍率为1∶70条件下，配制干密度为400 kg/m3的泡沫混凝土较为适宜，其抗压强度可达0．88 M Pa；掺入占胶凝材料质量0．1％的纤维素醚或占浆体体积0．1％的玻璃纤维，虽然泡沫混凝土的干密度有所增大，但其吸水率降低，抗压强度明显提高，分别可达1．34 M Pa和1．48 M Pa ．

Lots of aspects affect the properties of foamed concrete ,for the seek of improvinge the properties of foamed concrete ,water to binder ratio ,dilution ratio of foaming agent were investigated ,as well as the types and dosage of thickening agent and reinforcedenhanced fiber .The results show that when the water to binder ratio of 0 .3 and foaming agent dilution ratio of 1 :70 conditions ,foamed concrete of dry density is 400 kg/m3 would acquire the best properties .Its compressive strength can be achieved up to 0 .88MPa ;Mixed with 0 .1% cellulose ether by mass of the cementations material or 0 .1% glass fiber by volume of the paste ,the dry density of foamed concrete increased ,while its water absorption is lower ,the compres-sive strength increased significantly ,up to 1 .34 MPa and 1 .48 MPa ,respectively .
