Magnesium slag-based comprehensive repair mortar and preparation method thereof
The magnesium slag-based comprehensive repair mortar is prepared from the following raw materials: magnesium slag, mineral powder, fly ash, silica fume, recycled fine aggregate, sodium hydroxide, a polycarboxylic acid water reducing agent, an organic silicon defoaming agent, polyvinyl alcohol rubber powder, cellulose ether and water. The preparation method comprises the following steps: 1, weighing the raw materials except water, and stirring to obtain dry powder; 2, adding water into the dry powder, and stirring; according to the repair mortar, the hydration process of the magnesium slag and the mineral powder is utilized to promote the hydration of the fly ash and improve the increase of the later strength of the repair mortar, the expansion effect of magnesium oxide in the magnesium slag is utilized to counteract the interface contraction force in the hardening process of the repair mortar and improve the interface bonding strength, and meanwhile, by designing the components and content of the repair mortar, the repair mortar has good application prospects. Ordinary, quick-setting and self-compacting repair mortar is developed, multifunctional and multi-scene application of the repair mortar is realized, resource reutilization is realized, and raw material cost and energy consumption are reduced; the preparation process is simple, convenient and easy to implement.
本发明公开了一种镁渣基综合修补砂浆，包括以下组分原料：镁渣，矿粉，粉煤灰，硅灰，再生细骨料，氢氧化钠，聚羧酸减水剂，有机硅消泡剂，聚乙烯醇胶粉，纤维素醚，水；其制备方法为：一、称取除水以外的各原料搅拌得到干粉料；二、将水加入到干粉料中搅拌。本发明的修补砂浆利用镁渣与矿粉的水化过程促进粉煤灰水化，提高修补砂浆后期强度的增长，利用镁渣中氧化镁的膨胀作用，抵消修补砂浆硬化过程的界面收缩力，提高了界面粘接强度，同时通过对修补砂浆的组分及含量设计，开发出普通型、快凝型和自密实型修补砂浆，实现了修补砂浆的多功能、多场景应用，实现了资源再利用，降低了原料成本和能耗；本发明的制备工艺简单便捷，易于实现。
