Cement-based rapid repair material and preparation method thereof
The invention relates to the technical field of engineering materials, in particular to a cement-based rapid repair material and a preparation method thereof.The cement-based rapid repair material is prepared from, by mass, 42.55%-52.01% of sulphoaluminate cement, 2.25%-2.75% of silica fume, 44.80%-54.76% of river sand, 0.242%-0.284% of an early strength agent, 0.047%-0.053% of a defoaming agent and 0.116%-0.134% of a high-performance water reducing agent. The sulphoaluminate cement with the characteristics of rapid hardening and early strength is selected as the cementing material, and the composite early strength agent, the high-activity silica fume and the high-performance water reducing agent are doped, so that the cement-based rapid repair material can rapidly reach the standard strength in the early stage, can be used for emergency repair and construction projects, and can rapidly recover the operation functions of the projects.
本发明涉及工程材料技术领域，尤其涉及一种水泥基快速修复材料及其制备方法，其中水泥基快速修复材料，按照质量百分比计算，包括如下组分：硫铝酸盐水泥42.55%~52.01%，硅灰2.25%~2.75%，河砂44.80%~54.76%，早强剂0.242%~0.284%，消泡剂0.047%~0.053%和高性能减水剂0.116%~0.134%，本发明通过选用具有快硬、早强特性的硫铝酸盐水泥作为胶结料，并掺入复合型的早强剂，高活性的硅灰和高性能减水剂，使水泥基快速修复材料能够早期快速达到标准的强度，可用于抢修抢建工程，能够快速恢复工程运营功能。
