Dispersion-resistant repair mortar for underwater engineering as well as preparation method and application of dispersion-resistant repair mortar
The invention provides anti-dispersion repair mortar for underwater engineering as well as a preparation method and application of the anti-dispersion repair mortar. The anti-dispersion repair mortar for underwater engineering is prepared from the following raw material components in parts by weight: 60-120 parts of a cementing material, 40-80 parts of an active mixed material, 100-300 parts of fine aggregate, 1-4 parts of a water reducing agent, 3-12 parts of an anti-dispersion agent and 30-80 parts of water. The sulphoaluminate cement-Portland cement-gypsum ternary composite material is used for replacing traditional Portland cement, and the ternary composite material has good rapid setting, rapid hardening and shrinkage compensation performance and has a good application scene in the field of repairing mortar.
本发明提供一种水下工程用抗分散修补砂浆及其制备方法和用途，所述水下工程用抗分散修补砂浆包括如下重量份的原料组分：胶凝材料60～120份、活性混合材40～80份、细骨料100‑300份、减水剂1～4份、抗分散剂3～12份、水30～80份。本发明使用硫铝酸盐水泥‑硅酸盐水泥‑石膏三元复合材料替代传统硅酸盐水泥，三元复合材料具有良好快凝、快硬、收缩补偿性能，在修补砂浆领域具有良好应用场景。
