Self-leveling anti-crack mortar and preparation method thereof
The invention provides self-leveling anti-crack mortar and a preparation method thereof. The self-leveling anti-crack mortar is prepared from the following components in parts by weight: 800 to 900 parts of building gypsum, 50 to 200 parts of modified cement, 50 to 100 parts of fly ash, 30 to 100 parts of rubber particles, 0.5 to 1.25 parts of polypropylene fiber, 1 to 3 parts of a water reducing agent, 0.5 to 0.8 part of cellulose ether, 0.5 to 1.5 parts of a retarder, 0.05 to 0.15 part of dispersible rubber powder and 0.3 to 1.0 part of a de-foaming agent. The building gypsum is used as a main material, so that the early strength is ensured; by adding the water reducing agent, the defoaming agent and the dispersible rubber powder, the constructability and compactness of the mortar are greatly improved; through the synergistic effect between the rubber particles and the polypropylene fibers, internal stress generated by mortar hardening is reduced, and mortar cracks and deformation are prevented.
本发明提供了一种自流平抗裂砂浆及其制备方法，按重量份包括：建筑石膏800‑900份，改性水泥50‑200份，粉煤灰50‑100份，橡胶颗粒30‑100份，聚丙烯纤维0.5‑1.25份，减水剂1‑3份，纤维素醚0.5‑0.8份，缓凝剂0.5‑1.5份，可分散胶粉0.05‑0.15份，消泡剂0.3‑1.0份；本发明使用建筑石膏作为主要材料，保证了其早期强度；通过添加减水剂、消泡剂、可分散胶粉，大大改善了砂浆的施工性以及密实度；通过橡胶颗粒和聚丙烯纤维之间的协同作用，减小了砂浆硬化产生的内应力，防止砂浆裂纹产生和变形。
