Geopolymer-based rapid repair mortar and preparation method thereof
The invention discloses geopolymer-based rapid repair mortar which comprises ash powder and water, and the ash powder comprises the following raw materials: 40%-45% of a cementing material, 48%-60% of machine-made sand, 0.1%-0.15% of cellulose ether, 0.1%-0.15% of sodium aluminate, 0.2%-0.5% of water glass, 0.1%-0.3% of sodium hydroxide and 0.12%-0.2% of a water reducing agent; the geopolymer-based rapid repair mortar prepared by the invention has the following advantages: (1) the geopolymer-based rapid repair mortar is high in early strength and rapid to harden; (2) the binding power of new and old concrete is good, and the local repairing effect is ensured; (3) the construction is rapid, convenient and simple, and large machines and appliances are not needed; (4) the maintenance time after construction is short; (5) the wear resistance is high, and the durability is good; (6) the shrinkage is small, and the later strength performance is stable; (7) solid waste nickel slag, steel slag, construction waste and the like are used as materials, the cost is low, and environmental protection is facilitated.
本发明公开了一种地聚物基快速修补砂浆，包括灰粉和水，所述灰粉包括以下组份的原料：胶凝材料40‑45%，机制砂48‑60%，纤维素醚0.1‑0.15%，铝酸钠0.1‑0.15%，水玻璃0.2‑0.5%，氢氧化钠0.1‑0.3%，减水剂0.12‑0.2%；本发明制备的该地聚物基快速修补砂浆具有以下优点：（1）早期强度高，硬化快；（2）新旧混凝土的粘结力好，保证局部修补效果；（3）施工快速、方便、简单，不需要大型机器用具；（4）施工后养护时间短；（5）耐磨性高、耐久性好；（6）收缩小，后期强度性能稳定；（7）使用固体废弃物镍渣、钢渣、建筑垃圾等作为材料，成本低，有利于环保。
