Anti-crack dry-mixed mortar and production process thereof
The invention relates to anti-crack dry-mixed mortar and a production process thereof, and belongs to the technical field of building materials. The anti-crack dry-mixed mortar comprises 400 to 450 parts of Portland cement, 1400 to 1450 parts of machine-made sand, 70 to 75 parts of fly ash, 30 to 90 parts of trilobal polypropylene fiber, 60 to 180 parts of brucite fiber, 30 to 60 parts of pure acrylic copolymer emulsion powder, 0.9 to 1.6 parts of cellulose ether and 6 to 12 parts of a high-efficiency naphthalene water reducer. The production process of the anti-cracking dry-mixed mortar comprises the following steps: S1, mixing brucite fibers with a high-efficiency naphthalene water reducer in parts by weight to obtain a mixture; and S2, uniformly mixing the mixture obtained in the step S1 with other components in parts by weight. The anti-crack dry-mixed mortar has the effect of high anti-cracking performance.
本发明涉及一种抗裂干混砂浆及其生产工艺，属于建筑材料的技术领域，一种抗裂干混砂浆，其包括硅酸盐水泥400‑450份，机制砂1400‑1450份，粉煤灰70‑75份，三叶型聚丙烯纤维30‑90份，水镁石纤维60‑180份，纯丙烯酸共聚物乳胶粉30‑60份，纤维素醚0.9‑1.6份，高效萘系减水剂6‑12份；一种抗裂干混砂浆的生产工艺，包括以下步骤：S1：将水镁石纤维与高效萘系减水剂按重量份比例混合，得到混合物；S2：按重量份将步骤S1得到的混合物与其他组分混匀，本发明具有抗裂性能强的效果。
