Abstract:
Therefore, the activity test of the sedimentary fly ash aerated concrete is made by used co-doping, namely meantime adding mineral admixture and chemical activator. Best content of SHS, GS and NaCl are 27.0~36.0 g, 18.0~45.0 g, 4.5 g respectively. The strength of co-doping test is increased when the amount of silica sand is deducted from lime content and the fly ash content is fixed.
