    摘要:通過測試磷酸鉀鎂水泥(MKPC)凈漿流動度、強度變化、水化溫度變化、體積變形、耐水性和微觀形貌,研究了水玻璃對大流動性MKPC凈漿物理力學性能及顯微結構的影響。結果表明:水玻璃溶液能在保持MKPC快硬早強的基礎上大幅增加流動度,并能提高硬化體強度,使結構更加致密,耐水性改善。

    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.
    Key words:MKPC,high fluidity,sodium silicate
