Abstract：The granite powder and cement are used as cementitious materials to prepare high strength foamed concrete wall-board. The activity priming action of granite powder was stimulated by analyzing water glass,the effects of foam density,granite powder content and water glass content on the average pore size and compressive strength of foamed concrete were studied,to ob-tain mix ratio of high-strength foam concrete wallboard. The results show that when the granite powder and cement account for 30% and 70% of the cementitious material respectively,the water-cement ratio is 0.35,the foam density is 50 g/L,the dosage of the water reducing agent is 0.8%,the water glass modulus is 1.2,and the amount is 2.5%,the prpeared foamed concrete with wet denstity of 600 kg/m3has 28 d compressive strength of 3.9 MPa.
