摘要本工作从原材料以及表面修饰材料等探究了石膏基自流砂浆表面的耐磨性能。研究了可再分散性乳胶粉、石膏缓凝剂、普通硅酸盐水泥和固化剂对石膏基自流平砂浆耐磨性的影响,分析了砂浆流动度和抗压强度以及胶凝材料对石膏基自流平砂浆耐磨性的影响。结果表明,可再分散性乳胶粉对石膏基自流平砂浆的耐磨性有提高的作用。石膏缓凝剂会增加砂浆的离析沉降程度,从而导致石膏基自流平砂浆耐磨性降低。在以石膏为主的自流平砂浆中,适量增加石膏和普通硅酸盐水泥的加入量都有提高石膏基自流平砂浆耐磨性的作用。在自流平砂浆表面涂刷渗透性固化剂可提高其表层的密实度和耐磨性能,颜色有所差异,这说明固化剂种类品质对石膏基自流砂浆平表面颜色差异影响较大。

Abstract: In this paper, the wear resistance of gypsum-based gravity mortar surface was explored from raw materials and surface modification materials. The effects of redispersible latex powder, gypsum retarder, ordinary Portland cement and curing agent on the wear resistance of gypsum-based self-leveling mortar were studied. The fluidity and compressive strength of mortar and the gel-based material were analyzed. The effect of self-leveling mortar wear resistance. The results show that the redispersible latex powder has an improved effect on the wear resistance of gypsum-based self-leveling mortar. The gypsum retarder increases the degree of segregation and sedimentation of the mortar, resulting in a decrease in the wear resistance of the gypsum-based self-leveling mortar. In the gypsum-based self-leveling mortar, the appropriate amount of gypsum and ordinary Portland cement added has the effect of improving the wear resistance of the gypsum-based self-leveling mortar; however, reducing the amount of gypsum or ordinary Portland cement material. It is beneficial to improve the wear resistance of gypsum-based self-leveling mortar. Applying a permeable curing agent on the surface of the self-leveling mortar can improve the compactness and wear resistance of the surface layer. Apparently, the color is different, which is mainly reflected in the influence of the quality of the curing agent on the color difference of the gypsum-based gravity mortar.

Key words: gypsum base self-leveling wear-resisting performance fluidity strength surface mortar
