Masonry mortar for reducing saltpetering of plain brick wall and preparation method of masonry mortar
The invention relates to masonry mortar for reducing efflorescence of a bare brick wall and a preparation method of the masonry mortar. The masonry mortar comprises the following components in percentage by weight: 15%-25% of cement, 2%-5% of fly ash, 1%-2% of silica fume, 60%-80% of sand, 0.01%-0.1% of a water reducing agent, 0.1%-0.4% of redispersible rubber powder, 0.1%-0.4% of water-soluble fluoride and 0.01%-0.1% of a waterproof agent. By adding the redispersible rubber powder and the siloxane waterproof agent, a protective film can be formed inside and outside the mortar, the migration of water in the masonry mortar is reduced, and alkali ions are prevented from being enriched on the surface of a brick wall along with the migration of the water. In the masonry mortar formula disclosed by the invention, all the components have a synergistic effect, so that the saltpetering probability of the plain brick wall is reduced from multiple aspects, and the problem that saltpetering is easily caused during masonry of the traditional plain brick wall can be effectively solved.
本发明涉及一种用于减少清水砖墙泛碱的砌筑砂浆及其制备方法，该砌筑砂浆的各组分重量百分比为：水泥15%~25%，粉煤灰2%~5%，硅灰1%~2%，砂子60%~80%，减水剂0.01%~0.1%，可再分散胶粉0.1%~0.4%，水溶性氟酸盐0.1%~0.4%，防水剂0.01%~0.1%。通过添加可再分散胶粉和硅氧烷类的防水剂，能在砂浆内外形成保护膜，减少水分在砌筑砂浆内部的迁移，避免碱离子随水分迁移而富集在砖墙表面。本发明的砌筑砂浆配方中，各成分之间协同作用，从多个方面降低清水砖墙泛碱的概率，能够有效解决传统清水砖墙砌筑容易泛碱的问题。
