Experimental Research of Foaming Concrete Performance with Different Fly Ash

Abstract:

Low-density foam concrete is inorganic silicate material that can replace traditional organic materials for external wall insulation system. Based on the analysis of structure formation mechanism of foaming foam concrete prepared with chemical method, investigation by a large number of comparative tests and quantitative analysis, quantitative relationship of compressive strength, tensile strength, and blowing agent dosage quantitative of 3d, 7d and 28d foaming concrete are analyzed. The relationship between blowing agent and foam concrete strength and thermal conductivity variation is revealed by the research of doped fly ash concrete strength, improved workability mechanism. And further, independent sealing pores, high mechanical strength of pore wall, pore structure approximate to sphere and pore diameter with similar and small size were all favorable factors for higher strength of foam concrete.
