Gypsum self-leveling mortar with high leveling precision for building construction
The invention belongs to the technical field of building construction mortar application, and particularly discloses high-leveling-precision gypsum self-leveling mortar for building construction, which is prepared by mixing the following components: high-strength gypsum, anhydrous gypsum, quartz sand, kaolin, aluminum sulfate, alum, methylcellulose, redispersible latex powder, a water reducing agent, a defoaming agent, a retarder and the balance of water. The high-leveling-precision gypsum self-leveling mortar for building construction has the beneficial effects that the leveling precision is high, the fluidity is high, automatic leveling is realized, the flatness is extremely high, and more favorable conditions are provided for laying of various types of surface layer materials, so that the building quality is improved; the thickness is controllable, the shrinkage rate is smaller than 0.02%, one-time pouring can be carried out at any thickness of 3-60 mm, the effects of no cracking and no hollowing can be achieved, and the self-leveling application range is greatly widened; the product is high in strength and free of dusting, and can be freely controlled between 15MPa and 60MPa according to different environmental requirements, so that the adaptability of the product is improved.
本发明属于建筑施工砂浆应用技术领域，具体公开了一种找平精度高的建筑施工用石膏自流平砂浆，由以下组份的材料混合制得，高强石膏、无水石膏、石英砂、高岭土、硫酸铝、明矾、甲基纤维素、可再分散乳胶粉、减水剂、消泡剂和缓凝剂，余量为水。本发明的一种找平精度高的建筑施工用石膏自流平砂浆的有益效果在于：找平精度高，流动度高，自动流平，平整度极高，为各类型面层材料的铺设提供了更为有利的条件，从而提高了建筑品质；不开裂、不空鼓，厚度可控，收缩率小于0.02%，在3‑60mm任意厚度均可一次性浇筑，且可以做到不开裂、不空鼓，大大增加了自流平适应范围；强度高，不起灰，可根据不同环境要求，在15MPa至60MPa之间自由控制，提高了产品的适应性。
