Liquid alkali-free accelerator and preparation method thereof
The invention relates to the technical field of concrete admixtures, in particular to a liquid alkali-free accelerator and a preparation method thereof. The liquid alkali-free setting accelerator comprises the following components in parts by weight: 48.0 to 55.0 parts of aluminum-containing salt; 0 to 2.0 parts by weight of a hydroxide; 8.0 to 16.5 parts by weight of an inorganic acid; 0.8 to 4.6 parts by weight of an organic alcohol amine; 0.7 to 1.2 parts by weight of a rheological agent; 0.5 to 2.0 parts by weight of a dispersant; and 27.0 to 35.0 parts by weight of water. The liquid alkali-free accelerator has relatively short neat paste setting time and excellent mortar early-stage compressive strength, and has good adaptability to ordinary Portland cement.
本发明涉及混凝土外加剂技术领域，特别涉及一种液体无碱速凝剂及其制备方法。其中，液体无碱速凝剂，包含48.0～55.0重量份的含铝盐；0～2.0重量份的氢氧化物；8.0～16.5重量份的无机酸；0.8～4.6重量份的有机醇胺；0.7～1.2重量份的流变剂；0.5～2.0重量份的分散剂；27.0～35.0重量份的水。本发明制备的液体无碱速凝剂具有较短的净浆凝结时间，优异的砂浆早期抗压强度，对普通硅酸盐水泥具有良好的适应性。
