摘要
TK-1型速凝剂通过促使水泥浆体中迅速生成钙矾石而导致速凝,采用β-半水石膏取代该速凝剂中的元明粉后不改变速凝机理。调整后的速凝剂促进矿渣与Ca(OH)2的反应。
TK1 setting accelerator accelerates the course of setting as a result of promoting the quick formation of ettringite crystals in cement pastes.The replacement of anhydrous sodium sulphate by βhemihydrate gypsum in TK1 setting accelerator does not change the mechanisms of quick setting.The adjusted setting accelerator helps blast furnace slags to act with Ca(OH)2 and is of advantage for increasing the 28th day compressive strength.
