Quick-setting repair mortar for cement concrete bridge bottom plate cracks and preparation process of quick-setting repair mortar
The invention relates to the technical field of building materials, in particular to quick-setting repair mortar for cement concrete bridge bottom plate cracks and a preparation process of the quick-setting repair mortar. The preparation method comprises the following steps: uniformly mixing sulphoaluminate cement, quartz sand, polypropylene fiber and a mineral admixture to obtain a dry mortar material, uniformly mixing a polymer emulsion, an early strength agent, a water reducing agent, a defoaming agent, nano titanium dioxide and water to obtain a composite solution, pouring the composite solution into the dry mortar material, and fully stirring to obtain the mortar. Therefore, the synergistic effect of the composite solution and the mortar dry material is realized, and the uniformity and stability of the mortar are effectively improved. The prepared quick-setting repair mortar can quickly fill cracks of a cement concrete bridge bottom plate and has excellent strength, so that the safety of a bridge is improved, and the service life of the bridge is prolonged.
本发明涉及建筑材料技术领域，具体为一种水泥混凝土桥底板裂缝用快凝修补砂浆及其制备工艺。本发明通过将硫铝酸盐水泥、石英砂、聚丙烯纤维和矿物掺合料混合均匀作为砂浆干料，将聚合物乳液、早强剂、减水剂、消泡剂、纳米二氧化钛份和水混合均匀作为复合溶液，将复合溶液倒入砂浆干料中，并进行充分搅拌，以实现复合溶液和砂浆干料的协同作用，有效地提高了砂浆的均匀性和稳定性。本发明制备的快凝修补砂浆能够快速填补水泥混凝土桥底板的裂缝，并具有优异的强度，从而提高了桥梁的安全性和使用寿命。
