Research on the Properties of Non-autoclaved Aerated Concrete Prepared by Alkali Activated Phosphorus Slag

JIANG Xiao-jun 1,YAN Yun1,2,HU Zhi-hua 1,2(1.School of Materials Science and Engineering,Southwest University of Science and Technology,Mianyang 621010,China;2.State Key Laboratory Cultivation Base for Nonmetal Composites and Functional Materials,Mianyang 621010,China)  
The study examined the feasibility of manufacturing aerated concrete using alkali activated phosphorus slag as a cementitious material.The concentration of fly ash,modulus of sodium silicate solution and concentration of alkalis and curing procedure on the compressive strength and bulk density of aerated concrete have been studied.Moreover,the types of the hydration products were investigated using XRD and SEM.The results indicate that the compressive strength of aerated concrete was influenced by concentration of alkalis obviously.The compressive strength of 11.9 MPa and the bulk density of 806 kg/m3 were achieved under the circumstance of 60 ℃ curing,1.2 modulus of sodium silicate and 6% concentration of alkalis.
