Preparation method of waste glass mortar and waste glass mortar
The invention provides a preparation method of waste glass mortar and the waste glass mortar, and the method comprises the following steps: (1) uniformly mixing mixed alkali with Na2SO4, then uniformly mixing with waste glass powder, and putting the mixture into a high-pressure kettle for hydrothermal treatment; drying the activated glass powder in a constant temperature box, and grinding the dried glass powder into micro powder of 75-300 microns; (2) pouring the activated and ground glass powder, ordinary Portland cement and standard sand into a stirrer for mixing and stirring, then adding water, and continuously stirring to obtain waste glass mortar subjected to physical-chemical-hydrothermal combined activation; the mass ratio of the ordinary Portland cement to the standard sand to the glass powder to the Na2SO4 to the mixed alkali to the water is 1 : (1.575-2.025) : (0.225-0.675) : (0-0.06) : (0-0.06) : 0.47. The waste glass mortar prepared through the scheme is good in compression resistance and breaking strength, the expansion rate of the mortar is lower than a standard threshold value, recycling of waste glass is achieved, and great environmental protection significance is achieved. The waste glass mortar is reasonable in design, easy to operate and high in practicability.
本发明提供一种废弃玻璃砂浆的制备方法及废弃玻璃砂浆，方法包括：(1)将混合碱与Na2SO4均匀混合，随后与废弃玻璃粉混合均匀，将混合物放入高压釜中进行水热处理；将激活后的玻璃粉放入恒温箱中烘干，研磨成75～300μm微粉；(2)将激活并研磨后的玻璃粉与普通硅酸盐水泥、标准砂倒入搅拌机内混合搅拌，随后加入水，再继续进行搅拌，得到物理‑化学‑水热联合激活的废弃玻璃砂浆；所述普通硅酸盐水泥、标准砂、玻璃粉、Na2SO4、混合碱和水的质量比为1：(1.575～2.025)：(0.225～0.675)：(0～0.06)：(0～0.06)：0.47。通过本方案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。
