防水剂对干粉砂浆泛碱抑制的研究

Study on Restraining the Efflorescence of Ready-mixed Mortar by Using Waterproofing Agent

从干粉砂浆泛碱的成因出发,研究了硅烷防水剂对砂浆泛碱的抑制效果以及加入防水剂对砂浆力学性能的影响。试验结果表明,防水剂的加入可以有效地降低砂浆泛碱的程度,对砂浆的力学性能没有明显影响,说明硅烷防水剂也可以是一种有效的泛碱抑制剂。

Based on the causes of efflorescence of ready mixed mortar, the restraining effect of silane waterproofing agent on efflorescence of mortar was studied. And the influence on the mechanical properties of mortar was also studied. The experimental results show that the silane waterproofing agent can effectively decrease the degree of efflorescence of mortar, and the mechanical properties of mortar are still very well after the silane waterproofing agent to be blended in.
