Anti-crack mortar and preparation method thereof
The invention relates to anti-crack mortar and a preparation method thereof. The concrete comprises the following components: cement, a water reducing agent, a waterproof emulsion, aggregate, cellulose, toughening fiber, alkali lignin, fly ash, a calcium sulphoaluminate expanding agent, glass powder and water. The surfaces of the glass powder microparticles are smooth, so that the pumpability and the fluidity of the mortar in the injection molding process can be improved; the waterproof emulsion is gradually solidified and forms a net film structure, and a complex interlaced space net structure is formed, so that the interface structure of the mortar is improved, the bonding strength is improved, and cracking is reduced; a silane layer is formed on the surface of the toughening fiber, so that the surface hydrophilicity and roughness of the fiber are improved, the toughening fiber can be more firmly combined with cured mortar, the mechanical anchoring effect at an interface is improved, the dispersing performance of the fiber is also improved, the fiber surface treated by silane has higher activity, the interface with cement becomes more compact, and the toughness of the fiber is improved. Microcracks are reduced, and the adhesive force between the two is improved.
本发明涉及一种抗裂砂浆及其制备方法。它包括以下组成成分：水泥、减水剂、防水乳液、骨料、纤维素、增韧纤维、碱木质素、粉煤灰、硫铝酸钙膨胀剂、玻璃粉、水。玻璃粉微颗粒表面光滑，能够增大注摸过程中砂浆泵送性和流动性；防水乳液会逐步凝固并形成网膜结构，并形成交织复杂的空间网络结构，既改善了砂浆的界面结构，提高了粘结强度，减少开裂；在增韧纤维表面形成硅烷层，增加了纤维的表面亲水性和粗糙度，这样增韧纤维可以与固化的砂浆更牢固的结合，改善界面处的机械锚固作用，还提高了纤维的分散性能，经硅烷处理过的纤维表面具有更高的活性，与水泥界面变得更密实，微裂缝减少，两者间的黏附力得到改善。
