摘要
The aim of this study was to create a foaming agent and then evaluate its performance.This foaming agent is made up of Sodium lauryl sulfate,Ethanol,Lauryl alcohol and Water.On aeration,the diluted foaming solution produces a stable foam whose properties,density,capacity and drainage were studied.The compressive strength,water absorption and density of foamed concrete were also studied.Test results show that the initial foam density is 104kg/m3 at an optimum dilution ratio of 1:40.Foamed concrete’s density can vary from 450kg/m3 to 1 950bkg/m3 and its compressive strength is in0.5~23 MPa.Compressive strength test results of this foaming agent are higher than those produced with EABASSOC foaming agent.According to ASTM 869-91,this chemical composition qualifies to be used as a foaming agent.

On aeration, the diluted foaming solution produces a stable foam whose properties, density, capacity and drainage were studied. The compressive strength, water absorption and density of foamed concrete were also studied. Test results show that the initial foam density is 104 kg/m^3 at an optimum dilu- tion ratio of 1：40. Foamed concrete＇s density can vary from 450 kg/m^3 to 1 950 bkg/m^3 and its compressive strength is in 0. 5~23 MPa. Compressive strength test results of this foaming agent are higher than those produced with EABASSOC foa- ming agent. According to ASTM 869-91, this chemical composition qualifies to be used as a foaming agent.
