Self-leveling mortar and preparation method thereof
The invention provides self-leveling mortar and a preparation method thereof, and relates to the technical field of mortar manufacturing. The preparation method of the self-leveling mortar comprises the following steps: uniformly mixing and stirring the gypsum, the cement, the river sand, the inorganic filler and the carbon fibers to obtain a mixture; uniformly mixing and stirring a defoaming agent, a water reducing agent, a retarder, a stabilizer and a flow aid to obtain a composite additive; and adding the composite additive into the mixture at a constant speed while stirring the mixture, and keeping stirring until the mixture and the composite additive are uniformly mixed to obtain the self-leveling mortar. The prepared self-leveling mortar is added with the inorganic filler, so that the self-leveling mortar has good compressive strength and durability. In addition, due to the addition of the carbon fibers, the prepared self-leveling mortar has the advantage of being not prone to cracking. And finally, when the prepared self-leveling mortar is added with water for preparation and use, water bleeding and layering are not easy to occur, and the uniformity and the stability are relatively good.
本发明提供了一种自流平砂浆及其制备方法，其涉及砂浆制造的技术领域。自流平砂浆的制备方法包括：将石膏、水泥、河砂、无机填料、碳纤维混合搅拌均匀，获得混合料；将消泡剂、减水剂、缓凝剂、稳定剂、助流剂混合搅拌均匀，获得复合添加剂；在对混合料进行搅拌的状态下，向混合料中匀速加入复合添加剂并保持搅拌，直至混合料与复合添加剂混合均匀，获得自流平砂浆。本发明制备的自流平砂浆由于添加有无机填料，因此其具有良好的抗压强度和耐久性。此外，本发明制备的自流平砂浆由于碳纤维的添加，还具有不易开裂的优势。最后，本发明制备的自流平砂浆在被加水配制使用时，其不易出现泌水分层，均匀性和稳定性较好。
