Powdery alkali-free accelerator and preparation method thereof
The invention relates to a powdery alkali-free accelerator and a preparation method thereof, and the powdery alkali-free accelerator comprises the following raw materials in parts by weight: 100300 parts of magnesium-aluminum hydrotalcite, 500-700 parts of aluminum sulfate, 50100 parts of hydrated calcium silicate, 2080 parts of an early strength component, 13 parts of a water retention component, 520 parts of a coagulation accelerating component and 50-200 parts of a water absorption component. The powdery alkali-free accelerator can greatly improve the early strength of sprayed concrete and improve the sprayability of the sprayed concrete while reducing the use amount of cement, has a good early strength effect and an excellent coagulation accelerating effect, and has important significance for infrastructure facilities.
本发明涉及一种粉状无碱速凝剂及其制备方法，所述粉状速凝剂按重量份数计，包括以下原料：100300份镁铝水滑石、500‑700份硫酸铝、50100份水化硅酸钙、2080份早强组分、13份保水组分、520份促凝组分和50‑200份吸水组分。本发明的粉状无碱速凝剂在降低水泥用量的同时，可大幅提高喷射混凝土的早期强度，改善喷射混凝土的可喷性，具有良好的早强效果和优异的促凝作用，对于基建设施有着重要的意义。
