Quick-setting cement-based repairing material and preparation method thereof
The invention provides a quick-setting cement-based repairing material and a preparation method thereof, and belongs to the technical field of repairing materials. The quick-setting cement-based repairing material is prepared from the following components in percentage by weight: 10 to 60 percent of cement, 0.5 to 10 percent of silica fume, 1.5 to 10 percent of viscosity-reducing microbeads, 1 to 15 percent of steel slag powder, 25 to 65 percent of aggregate, 1 to 30 percent of quick-setting early strength agent, 0.1 to 1.0 percent of calcium oxide, 0.05 to 3.0 percent of adhesive, 0.03 to 4.0 percent of fiber, 0.01 to 0.15 percent of defoaming agent and 0.05 to 3.0 percent of water reducing agent. The quick-setting cement-based repairing material provided by the invention is novel repairing mortar which has the cohesiveness of a high polymer material and the durability of an inorganic material, not only can effectively overcome the defects that sulphoaluminate cement is short in setting time and easy to shrink, but also has the characteristics of quick setting, early strength, high bonding strength, strong durability, good wear resistance, low shrinkage, cracking resistance and the like.
本发明提供了一种速凝型水泥基修补材料及其制备方法，属于修补材料技术领域。本发明的速凝型水泥基修补材料由以下重量百分比的组分构成：水泥10～60％、硅灰0.5～10％、降粘微珠1.5～10％、钢渣粉1～15％、骨料25～65％、速凝早强剂1～30％、氧化钙0.1～1.0％、胶粘剂0.05～3.0％、纤维0.03～4.0％、消泡剂0.01～0.15％和减水剂0.05～3.0％。本发明提供的速凝型水泥基修补材料既具有高分子材料的粘结性，又具有无机材料耐久性的新型修补砂浆，不仅能有效克服硫铝酸盐水泥凝结时间短、易倒缩的缺点，还具有快凝早强、粘结强度高、耐久性强、耐磨性好、低收缩抗开裂等特点。
