Superfine metakaolin-alkali slag mortar as well as preparation method and application thereof
The invention relates to superfine metakaolin-alkali slag mortar as well as a preparation method and application thereof. The superfine metakaolin-alkali slag mortar comprises the following raw materials in parts by mass: 400-500 parts of a gel material, 1200-1400 parts of standard sand, 100-220 parts of an alkali activator and 100-200 parts of water, wherein the gel material comprises slag and superfine metakaolin, and the replacement amount of the superfine metakaolin is 5%-15% of the total mass of the gel material. The superfine metakaolin with smaller particle size is dispersed among slag particles, so that the hydration of the slag is slowed down in the early stage of hydration, and the coagulation time is prolonged. And in addition, the concrete has high fluidity, high strength and high compactness, and has wide application prospects in the building fields of high-rise buildings, offshore buildings, cross-sea bridges and the like.
本发明涉及一种超细偏高岭土‑碱矿渣砂浆及其制备方法和应用，它的原材料按质量分数计包括400‑500份凝胶材料、1200‑1400份标准砂、100‑220份碱激发剂、100‑200份水；其中，所述凝胶材料包括矿渣和超细偏高岭土，所述超细偏高岭土替代量为胶凝材料总质量的5％‑15％。本发明采用粒径较小超细偏高岭土分散在矿渣颗粒中间，在水化前期减缓矿渣水化，延长凝结时间。而且具有高流动度、高强度和高密实性，对于高层建筑，近海建筑，跨海大桥等建筑领域具有广泛的应用前景。
