Preparation and Performance Testing of Foamed Concrete

摘要：

　　The key influences of foamed concrete and the optimum preparation technology were studied.The performance of foamed concrete was analyzed by the compressive strength testing,SEM.Results show that the flowability of cement paste is good when water-cement ratio is 0.4.The amount of foam added in sulphoaluminate cement is not able to exceed 3.5L/kg.However,the dilution multiple of foaming agent is near concentration and the mixing time depends on the foam quantity.When the water-cement ratio is 0.4,the foam quantity is 3 L/kg and the foaming agent is diluted 30 times.When the mixing time is 60s,the dry density is around 380kg/m3 and the 7d compressive strength reaches to 0.9MPa.
