摘　　要：为了解决泡沫混凝土遇水浇筑时浆体和气泡群分离的问题,在泡沫混凝土中掺加可塑剂形成塑化型泡沫混凝土。本论文提出了一种试验方法,对影响塑化型泡沫混凝土抗压强度的因素进行研究。通过单因素试验分析,讨论了水胶比、胶砂比、减水剂掺量、可塑剂掺量、微生物多糖种类和掺量、矿物掺合料种类和掺量对塑化型泡沫混凝土28 d龄期抗压强度的影响。研究结果表明配比合理的塑化型泡沫混凝土可在水下浇筑成型并且产生强度,满足工程的要求。In order to solve the problem that Foamed Concrete may be easily dispersed under water,the plasticizer admixture can be used to form Plasticizing Foamed Concrete. This paper reports a study on the factors affecting the compressive strength,especially Water-cement ratio,Cment-sand ratio,the dosage of water-reducing admixture and plasticizer admixture,the type and dosage of biopolymers and mineral admixtures,by designing the test apparatus and methods. The results showed that Plasticizing Foamed Concrete can significantly improve resistance to dispersion and maintain a certain compressive strength.The properties of Plasticizing Foamed Concrete can meet the requirements of engineering.
