Alkali-free liquid accelerator as well as preparation method and application thereof
The invention relates to an alkali-free liquid accelerator as well as a preparation method and application thereof, and belongs to the technical field of building material admixtures. The invention relates to an alkali-free liquid accelerator. The alkali-free liquid accelerator comprises aluminum salt, alcohol amine, a suspending agent, a pH regulator, a nano material and water, wherein the nano material comprises at least one of nano zeolite or modified nano zeolite. The nano material is added into the alkali-free liquid accelerator, so that the hydration degree of cement and the structural regulation and control of a hydration product are improved, the generation of calcium silicate gel and calcium aluminate gel is promoted, the porosity of sprayed concrete is reduced, the early strength and impermeability of the sprayed concrete are improved, and the alkali-free liquid accelerator has a good application prospect.
本发明涉及一种无碱液体速凝剂及其制备方法和应用，属于建筑材料外加剂技术领域。一种无碱液体速凝剂，所述无碱液体速凝剂包括：铝盐、醇胺、悬浮剂、pH调节剂、纳米材料和水；其中，所述纳米材料包括纳米沸石或改性纳米沸石中的至少一种。本申请在无碱液体速凝剂中加入纳米材料，提高水泥的水化程度和水化产物结构调控，促进了硅酸钙凝胶和铝酸钙凝胶的生成，减少了喷射混凝土的孔隙率，提高了喷射混凝土的早期强度和抗渗性能，具有良好的应用前景。
