Liquid accelerator as well as preparation method and application thereof
The invention discloses a liquid accelerator and a preparation method thereof. The liquid accelerator is prepared from the following raw materials: a solution containing metaaluminate, aluminum sulfate, an inorganic acid solution, a complexing stabilizer, water, an optional anti-settling agent and an optional acidity neutralizer. The liquid low-alkali accelerator provided by the invention has theadvantages of rapid cement setting and hardening, rapid development of early strength of sprayed concrete, basically no loss of later strength and the like at a relatively low mixing amount, has widecement adaptability, and can still provide excellent rapid hardening and early strength properties for cement with low C3A content; the liquid accelerator has the advantages of no (low) corrosion, stable long-term storage performance, simple production process, easily controlled conditions, good economic benefit and wide application prospect.
本发明公开了一种液体速凝剂及其制备方法。该液体速凝剂的制备原料包括：含有偏铝酸盐的溶液、硫酸铝、无机酸溶液、络合稳定剂、水，以及任选的防沉剂和酸度中和剂。本发明提供的液体低碱速凝剂在较低掺量下即具有水泥凝结硬化快、喷射混凝土早期强度发展迅速、后期强度基本无损失等优点，而且具有广泛的水泥适应性，即使对于CA含量低的水泥仍能提供优良的快硬早强性能；该液体速凝剂无(低)腐蚀、长期存放性能稳定，且生产工艺简单，条件易控，具有良好的经济效益和广阔的应用前景。
