Study of the Density Control of the Low Density Sulphate Aluminium Cement (SAC) Foam Concrete

摘要

With enhancement of the energy conservation of the building and the external wall thermal insulation material fire protection level, the preparation of low density foam concrete has become the hot spot of the material engineer. The main factors, influencing the low density light foam concrete, include the selection and dosage of cementitous material and admixture, the volume of foam, water consumption and chemical admixture for concrete. This paper mainly discusses the effects of the dosage of water reducing agent, the admixture partly replacing SAC, the weight of water and binder and the volume proportion of slurry and foam on the density control of low density light foam concrete.
