Plastering mortar with anti-cracking performance for house building
The invention relates to the field of gypsum mortar, and particularly discloses plastering mortar with anti-cracking performance for house buildings, which comprises the following components in percentage by mass: 18-26% of cement, 36-42% of sand, 15-20% of water, 12-16% of talcum powder, 8-12% of glue and 1-2% of additive, the additive comprises polypropylene fiber and at least one of magnesium slag and lignin fiber. The polypropylene fiber has no contribution to the compressive strength of the mortar, but is beneficial to improving the early-stage crack resistance of the wall surface of the building, and improving the impact toughness and the impermeability; the particle size of the crushed magnesium slag is reduced, the specific surface area is large, native microcracks are left, good water absorption and water retention are achieved, and meanwhile the compressive strength of the mortar can be improved; although lignin fibers are low in strength, the lignin fibers are high in water absorption and water-retaining property and have a tying effect at the same time. Through the organic combination mode of the three, the water-retaining property and the crack resistance of the wall body can be improved at the same time, and the compressive strength is considered at the same time.
本发明涉及石膏砂浆领域，具体公开了一种房屋建筑抗裂性能的抹灰砂浆，包括质量占比为：18％‑26％的水泥、36％‑42％的砂、15％‑20％的水、12％‑16％的滑石粉、8％‑12％的胶水和1％‑2％外加剂，外加剂包括聚丙烯纤维以及包括镁渣和木质素纤维中的至少一者。聚丙烯纤维对砂浆的抗压强度无贡献，但是有助于改善建筑物墙面的早期抗裂性能，改善冲击韧性和抗渗性；碾碎后的镁渣粒径变小，比表面积大，且会残留原生微裂隙，有良好的吸水和保水性，同时能够提高砂浆的抗压强度；木质素纤维虽然强度低，但是吸水和保水性强，同时存在拉结效应。这三者之间的有机组合方式，可以同时提高墙体的保水性和抗裂性，同时兼顾抗压强度。
