【Abstract】 This paper investigated the influence of sodium silicate on the mechanical and physical performarnce and microstructure of high fluidity potassium and magnesium phosphate cement(MKPC) through testing its paste fluidity,strength,temperature change,volume deformation,water resistance and micromorphology. The results indicated that water glass solution can greatly increase the fluidity of MKPC without losing the characteristics of fast hardening and early strength,at the same time,it can increase strength,make the structure denser and improve the water resistance.更多还原
