Alkali-free accelerator for concrete and preparation method thereof
The alkali-free accelerator for concrete comprises the following components in percentage by weight: 45-55% of phosphate, 8-12% of polyacrylamide, 18-22% of aluminum sulfate, 8-12% of magnesium sulfate, 8-12% of ferrous sulfate, 4-6% of isopropanolamine, 4-6% of a stabilizer, 1-3% of a defoaming agent, 0.5-1.5% of propylene glycol, 0.5-3% of organic alcohol, 4-9% of isopropanolamine, 0.5-5% of nano silicon dioxide, 0.1-1.5% of a pH regulator, 0-1.5% of a defoaming agent and the balance of water. The whole formula is simple, the cost is low, the early strength of the concrete is remarkably improved, the solidification and hardening process of the concrete is accelerated, and the construction progress is accelerated. The components in the formula are alkali-free components, so that the risk of alkali hardening reaction in the concrete is effectively reduced, and the durability of the concrete is improved.
一种混凝土用无碱速凝剂，包括如下配比：磷酸盐45‑55％、聚丙烯酰胺8‑12％、硫酸铝18‑22％、硫酸镁8‑12％、硫酸亚铁8‑12％、异丙醇胺4‑6％、稳定剂4‑6％、消泡剂1‑3％、丙二醇0.5‑1.5％、有机醇0.5‑3％、异丙醇胺4‑9％、纳米二氧化硅0.5‑5％、pH调节剂0.1‑1.5％、消泡剂0‑1.5％、剩余为水。本发明整体配方简单，成本低，以显著提高混凝土的早期强度，加快混凝土的凝固和硬化过程，有助于加速施工进度。配方中的成分均为无碱成分，有效减少混凝土内部碱硬化反应的风险，提高混凝土的耐久性。
