水泥基快速修补砂浆研究

Research of cement-based rapid repairing mortar

为了对建筑工程混凝土进行快速修补,在普通硅酸盐水泥中加入纤维、膨胀剂、修补剂、掺合料等组成纤维复合掺合料,通过优化配比,得到水泥基快速修补砂浆,可以在一定程度上改善水泥砂浆的变形、凝结硬化、流动性及强度等性能,对于普通混凝土的修补,可以采取这一技术途径配制修补砂浆。

In order to repair concrete rapidly, composite admixtures include fiber, expansive agent, repairing agent and admixture are added in ordinary portland cement. By optimizing the proportion, cement-based rapid repairing mortar can be made. Some performances of the cement mortar such as deformation, setting and hardening, fluidity and strength can be improved to a certain extent. For ordinary concrete repairing,this approach to can be taken prepare the repairing mortar.
