胶凝材料影响水泥基饰面砂浆泛碱的研究进展

Research Development of the Influence of Cementitious Materials on the Efflorescence of Cement-based Decorative Plasters

介绍了胶凝材料影响水泥基饰面砂浆泛碱性能的研究进展。研究主要针对水泥基饰面砂浆的泛碱成因,从无机胶凝材料入手,探讨其对砂浆泛碱的影响和抑制泛碱的措施。涉及的无机胶凝材料主要集中在硅酸盐水泥、铝酸盐水泥及其分别或共同与石膏组成的二元和三元体系。水泥基饰面砂浆的抗泛碱主要通过两条途径,一是控制水化时Ca(OH)_2的产生,二是提高砂浆的密实度。

The research development of the influences of cementitious materials on the efflorescence of cementbased decorative plasters were introduced. According to the formation mechanism of efflorescence, the influence degrees and the curbing measured of efflorescence had been discussed. The inorganic gel materials involved mainly concentrated on Portland cement, alurninate cement and binary or ternary systems composed by the two kinds of cement jointly or respectively with gypsum. There are two ways to reduce efflorescence： one is to control the generation of Ca（OH）2 in hydration; the other is to improve the surface density of the mortar.
