Low-shrinkage high-adhesion alkali slag cement-based patching material and preparation method thereof
The invention belongs to the technical field of concrete repairing materials, and particularly relates to a low-shrinkage high-adhesion alkali slag cement-based repairing material and a preparation method thereof. The low-shrinkage and high-adhesion alkali slag cement-based repairing material is prepared from the following components in parts by mass: 25 to 35 parts of water, 25 to 30 parts of water glass, 100 parts of blast furnace slag micro powder, 10 to 20 parts of pre-carbonized regenerated micro powder, 5 to 10 parts of fluorgypsum, 150 to 300 parts of sand, 0.1 to 2 parts of polyacrylic acid emulsion, 0.3 to 1 part of water reducing agent, 0.5 to 2.0 parts of early strength agent and 0.1 to 1.0 part of retarder. The low-shrinkage high-bonding alkali slag cement-based repairing material is low in shrinkage rate and high in bonding strength, and the main materials are mainly solid wastes, so that the low-shrinkage high-bonding alkali slag cement-based repairing material is low in cost, easy to obtain and suitable for industrial production.
本发明属于混凝土修补材料技术领域，具体涉及一种低收缩高粘结碱矿渣水泥基修补材料及其制备方法。本发明的低收缩高粘结碱矿渣水泥基修补材料包括下述质量份的组分：水25‑35份、水玻璃25‑30份、高炉矿渣微粉100份、预碳化的再生微粉10‑20份、氟石膏5‑10份、砂150‑300份、聚丙烯酸乳液0.1‑2份、减水剂0.3‑1份、早强剂0.5‑2.0份和缓凝剂0.1‑1.0份。本发明的低收缩高粘结碱矿渣水泥基修补材料的收缩率低、粘结强度高，且主料以固体废弃物为主，成本低，易于获取，适合工业化生产。
