Building mortar and preparation method thereof
The invention is applicable to the technical field of building materials, and provides building mortar and a preparation method thereof. The formula of the building mortar comprises the following components: portland cement, sulphoaluminate cement, fine aggregate, coarse aggregate, limestone powder, basalt fiber, a composite water reducing agent, a retarder, a coagulant and water . The introducedbasalt fiber has the characteristics of high tensile strength, low manufacturing cost, environmental protection, excellent mechanical properties, corrosion resistance, high temperature resistance andthe like, and the strength of the building mortar can be effectively improved. The building mortar is high in early strength, and the flexural strength and compressive strength of the building mortarcan respectively reach 4MPa and 20MPa or above within 4h. The building mortar is low in expansion rate after being hardened, and expansion damage cannot occur.
本发明适用于建筑材料技术领域，提供了一种建筑砂浆及其制备方法，其配方包括以下组分：硅酸盐水泥、硫铝酸盐水泥、细骨料、粗骨料、石灰石粉、玄武岩纤维、复合减水剂、缓凝剂、促凝剂和水，本发明引入的玄武岩纤维抗拉强度高，造价低廉，绿色环保，有优异的力学性能、耐腐蚀、耐高温等特点，能够有效地增加建筑砂浆的强度。本发明所述建筑砂浆早期强度高，4h抗折、抗压强度分别能够达到4MPa和20MPa以上。本发明建筑砂浆硬化后膨胀率小，不会发生膨胀破坏。
