Experimental Research of Foam Concrete with Different Fly Ash Level

Based on the analysis of structure formation mechanism of foam concrete prepared with chemical method, investigations by a large number of comparative tests and quantitative analysis, quantitative relationship of compressive strength and fly ash dosage on 3d, 7d and 28d foam concrete specimens are analyzed. This investigation examined effect of fly ash that mixed into admixture concerning strength of low –density foam concrete. Mechanical test were performed to measure effect of fly ash on affecting compressive. Results indicate that fly ash significantly reducing compressive strength and increasing thermal conductivity of low-density foam concrete. Moreover, experimental results show that compressive strength of each group is more and smaller with the increase of the curing time.
