Premixed mortar mixture for buildings and preparation method thereof
The invention provides a premixed mortar mixture for buildings and a preparation method thereof, and relates to the technical field of building materials. The premixed mortar mixture for buildings comprises the following raw materials in parts by weight: 10-15 parts of cement, 20-25 parts of sintered brick powder, 10-14 parts of fly ash, 50-55 parts of quartz sand, 20-25 parts of crushed stone powder, 1-2 parts of a concrete admixture, 20-30 parts of water and 10-15 parts of a water-retaining thickener. By simultaneously adding the concrete admixture and the water-retaining thickener, the mortar mixture has water-retaining property, thixotropic lubricity and dispersion suspension property, meets the construction performance of mortar, has the characteristics of long-time storage and transportation resistance, high strength and low shrinkage rate, solves the difficult problem of construction waste treatment, and is simple in process steps, the method is friendly to the environment; and the production cost of the mortar is reduced.
本发明提供一种建筑用预拌砂浆混合料及其制备方法，涉及建筑材料技术领域。该筑用预拌砂浆混合料，包括以下重量份的原料：水泥10‑15份、烧结砖粉20‑25份、粉煤灰10‑14份、石英砂50‑55份、碎石粉20‑25份、混凝土外加剂1‑2份、水20‑30份、保水增稠剂10‑15份。通过同时添加混凝土外加剂、保水增稠剂使砂浆混合料具有保水性、触变润滑性、分散悬浮性，满足砂浆的施工性能，使预拌砂浆混合料具有耐长时间存储运输，且强度高、收缩率低的特点，解决了建筑垃圾处理的难题，工艺步骤简单，绿色环保且降低了砂浆生产成本。
