Gypsum self-leveling material and preparation method thereof
The invention provides a gypsum self-leveling material and a preparation method thereof. The raw materials of the self-leveling material comprise gypsum, sand and calcium carbonate, and can also comprise additives. Based on the total weight of the gypsum, the sand and the calcium carbonate being 100%, the weight of the gypsum is 35%-45%, the weight of the sand is 40%-47%, and the weight of the calcium carbonate is 15%-18%; the particle size of the sand is 40-100 meshes; and the particle size of the calcium carbonate is 270-600 meshes. The gypsum self-leveling material provided by the inventionhas good fluidity and constructability after being mixed with water, is relatively high in strength after being hardened, is flat, smooth and clean, is low in shrinkage rate, can effectively replacea traditional ground operation method, and is used for ground leveling or a ground heating system.
一种石膏自流平材料及其制备方法，所述自流平材料的原料含有石膏、砂和碳酸钙，还可以包含有外加剂。并且以石膏、砂和碳酸钙的总重量为100％计，其中的石膏的重量为35％‑45％，砂的重量为40％‑47％，碳酸钙的重量为15％‑18％；所述砂的粒度为40‑100目，所述碳酸钙的粒度为270‑600目。本申请提供的石膏自流平材料与水拌和后具有良好的流动性及施工性，硬化后强度较高，平整光洁，收缩率小，可有效取代传统地面作业方法，用于地面找平或地采暖系统。
