Rust-resistant high-strength special grouting mortar and preparation method thereof
The invention discloses rust-resistant high-strength special grouting mortar and a preparation method thereof. The method comprises the following steps: S1, weighing ordinary Portland cement, silica fume, fly ash bead powder, mineral powder and quartz sand, carrying out multiple experiments by adopting a self-adaptive graded reaction control algorithm, generating an ingredient combination and recording data; s2, evaluating ingredient combination performance by applying an optimization algorithm, and determining an optimal ingredient proportion; s3, weighing and mixing the dry powder according to the optimal proportioning proportion; s4, the mixture is conveyed to a stirring bin through an auger or an elevator, and PVA fibers, a PC-1051 type water reducing agent and a defoaming agent are added; s5, uniformly stirring by using a multi-level self-adaptive dispersion algorithm; s6, slurry performance is detected and recorded; and S7, qualified slurry is used for grouting construction. The problems that in the prior art, reinforcing steel bars are prone to corrosion, and the mechanical property of grouting mortar is insufficient are effectively solved, the corrosion resistance and the mechanical property of the mortar are remarkably improved, and the high requirements of modern building structures for durability and protection performance are met.
本发明公开了一种阻锈型高强特种灌浆砂浆及其制备方法。S1、称量普通硅酸盐水泥、硅灰、粉煤灰微珠粉、矿粉和石英砂，采用自适应分级反应控制算法进行多次实验，生成配料组合并记录数据；S2、应用优化算法评估配料组合性能，确定最佳配料比例；S3、按最佳配料比例称量并混合干粉；S4、通过绞龙或提升机输送至搅拌仓，添加PVA纤维、PC‑1051型减水剂和消泡剂；S5、使用多层次自适应分散算法均匀搅拌；S6、检测浆体性能并记录；S7、合格浆体用于灌浆施工。本发明有效解决了现有技术中钢筋易腐蚀及灌浆砂浆力学性能不足的问题，显著提高了砂浆的抗腐蚀性和力学性能，满足了现代建筑结构对耐久性和防护性能的高要求。
