High-corrosion-resistance maritime work repair mortar and preparation method thereof
The invention provides high-corrosion-resistance maritime work repair mortar and a preparation method thereof, and relates to the technical field of maritime work mortar. The high-belite sulphoaluminate cement mortar is prepared from the following components in parts by weight: 35 to 42 parts of high-belite sulphoaluminate cement, 0.5 to 2 parts of a cementing material, 50 to 60 parts of aggregate, 4 to 6.5 parts of asphalt modified rubber powder, 0 to 0.5 part of anhydrite, 0.15 to 0.2 part of a water reducing agent, 0.16 to 0.2 part of a retarder and 0.05 to 0.1 part of an early strength agent. According to the invention, the high belite sulphoaluminate cement is used as a repairing material for concrete cracks and defects, the modified asphalt rubber powder is used for replacing an epoxy emulsion in a traditional process, and the cementing material, the early strength agent and the like are compounded, so that the single-component high-corrosion-resistance maritime work repairing mortar is researched and developed. The mortar formula is simple, the raw material cost is low, a powder product is easy to produce, store and transport, and after concrete is repaired, the mortar has excellent adhesion, waterproofness and high salt corrosion resistance, so that the problem of poor durability of traditional repairing mortar is solved, and the problems of tedious construction process, labor waste and material waste of double-component polymer mortar are solved.
本发明提供了一种高抗蚀海工修补砂浆及其制备方法，涉及海工砂浆技术领域。按重量分数计，包括以下组分：高贝利特硫铝酸盐水泥35‑42份、胶结料0.5‑2份、骨料50‑60份、沥青改性胶粉4‑6.5份、无水硬石膏0‑0.5份、减水剂0.15‑0.2份、缓凝剂0.16‑0.2份、早强剂0.05‑0.1份。本发明采用高贝利特硫铝酸盐水泥作为混凝土裂缝和缺陷的修补材料，以改性沥青胶粉代替传统工艺中的环氧类乳液，复配使用胶结料和早强剂等，研发出一种单组份的高抗蚀海工修补砂浆。砂浆配方精简、原料成本低廉、粉体产品易于生产、储存和运输，而且修补混凝土后还具有优异粘接性，防水性，高耐盐腐蚀性，既解决了传统修补砂浆耐久性差的问题，又解决了双组份聚合物砂浆施工工艺繁琐、费工费料的问题。
