Self-repairing surface layer mortar and preparation method thereof
The invention discloses self-repairing surface mortar and a preparation method thereof, and belongs to the technical field of building materials. The mortar is prepared from the following raw materials: 180 to 230 parts of cement, 400 to 450 parts of aggregate, 80 to 110 parts of filler, 50 to 70 parts of redispersible latex powder, 30 to 50 parts of self-repairing silicon microspheres, 10 to 15 parts of polyvinyl alcohol fiber, 1 to 5 parts of defoaming agent, 0.5 to 1.5 parts of dispersing agent, 5 to 10 parts of composite expanding agent, 1 to 5 parts of water reducing agent, 1 to 3 parts of methyl hydroxypropyl cellulose ether and 80 to 100 parts of water. The surface mortar has the advantages of fast early strength development, high later strength, excellent mechanical properties, good wear resistance and strong impact resistance, and is suitable for various scenes.
本发明公开一种自修复面层砂浆及其制备方法，属于建筑材料技术领域。本发明砂浆包括以下原料：水泥180‑230份、骨料400‑450份、填料80‑110份、可再分散性乳胶粉50‑70份、自修复硅微球30‑50份、聚乙烯醇纤维10‑15份、消泡剂1‑5份、分散剂0.5‑1.5份、复合膨胀剂5‑10份、减水剂1‑5份、甲基羟丙基纤维素醚1‑3份、水80‑100份。本发明面层砂浆，早期强度发展快，后期强度较高，力学性能优异，耐磨性好、抗冲击能力强，适合各类场景使用。
