Waste glass mortar and preparation method thereof
The invention provides waste glass mortar and a preparation method thereof. The mortar comprises the following components in parts by weight: 0.8-1 part of ordinary Portland cement; 1.575-2.025 parts of standard sand; 0.225-0.675 part of glass powder; 0-0.06 part of Na2SO4; 0-0.06 part of mixed alkali; and 0.40-0.50 part of water. The preparation method comprises the following steps: uniformly mixing the ordinary Portland cement, the standard sand and the glass powder in proportion to obtain a dry material component A; uniformly mixing Na2SO4, mixed alkali and water according to a ratio to obtain a mixed solution B; and pouring the dry material component A into the mixed solution B, and uniformly stirring to obtain the waste glass mortar subjected to physical-chemical combined activation. The waste glass mortar prepared by the scheme of the invention is good in compressive strength and breaking strength, the expansion rate of the mortar is lower than a standard threshold value, the recycling of the waste glass is realized, and the waste glass mortar has great environmental protection significance. The design is reasonable, the operation is easy, and the practicability is high.
本发明提供一种废弃玻璃砂浆及其制备方法，所述砂浆以重量份数计包括以下组分：普通硅酸盐水泥：0.8~1份；标准砂：1.575~2.025份；玻璃粉：0.225~0.675份；Na2SO4：0~0.06份；混合碱：0~0.06份；水：0.40~0.50份。制备方法包括：将普通硅酸盐水泥、标准砂、玻璃粉按照比例混合均匀，得到干料组分A；将Na2SO4、混合碱和水按照比例混合均匀，得到混合溶液B；将干料组分A倒入混合溶液B中搅拌均匀，得到经物理‑化学联合激活的废弃玻璃砂浆。通过本发明方案所制备的废弃玻璃砂浆，抗压及抗折强度良好，砂浆的膨胀率低于规范阀值，实现了废弃玻璃的再利用，具有重大的环保意义。本发明设计合理，操作简单，实用性强。
