Cement early strength agent as well as preparation method and application thereof
The invention discloses a cement early strength agent as well as a preparation method and application thereof, and belongs to the technical field of building materials. The cement early strength agent provided by the invention is prepared from the following raw materials in parts by weight: 49-55 parts of degummed artificial stone powder; 1-2 parts of a surface modifier; the surface modifier comprises an agglomerated stone powder modifier and sodium carbonate; the median particle size of the solid in the cement early strength agent is 0.3-0.5 [mu] m. The cement early strength agent provided by the invention can effectively promote early hydration of cement, reduce the porosity of the cement, improve the flexural and compressive strength of the cement, and realize the purposes of reutilization of solid wastes in artificial stones and cost reduction at the same time. The invention also provides a preparation method and application of the cement early strength agent.
本发明公开了一种水泥早强剂及其制备方法和应用，属于建筑材料技术领域。本发明提供的水泥早强剂，按重量份计，制备原料包括：脱胶人造石材粉49～55份；表面改性剂1～2份；所述表面改性剂包括岗石石粉改性剂和碳酸钠；所述水泥早强剂中固体的中值粒径为0.3～0.5μm。本发明提供的水泥早强剂，能够有效促进水泥的早期水化，降低其孔隙率，提高其抗折抗压强度，同时实现了人造石材中固体废料的再利用及降低成本的目的。本发明还提供了上述水泥早强剂的制备方法和应用。
