Composite liquid early strength agent of white Portland cement
The invention relates to the technical field of white cement admixtures, in particular to a composite liquid early strength agent for white Portland cement, which comprises the following raw materials in parts by weight: 30-40 parts of reinforcing components, 5-10 parts of auxiliary solubilizing and stabilizing components and 50-65 parts of carriers, the total part number of the composite liquid early strength agent is 100, the reinforcing components are organic salt and inorganic salt reinforcing agents, and the auxiliary solubilizing and stabilizing components are inorganic salt reinforcing agents. The organic salt and inorganic salt reinforcing agent comprises sodium oxalate, sodium carbonate and magnesium fluosilicate, the auxiliary solubilizing and stabilizing group is a mixture of lignosulfonate and polyglycerol, the lignosulfonate is sodium lignosulfonate, and the polyglycerol is tripolyglycerol. The composite liquid additive is high in environmental friendliness, simple in preparation process and low in production cost, and can be used for preparing the composite liquid additive. The early (3d) strength of the white cement is improved by 10-15%, the white cement product curing time is saved, and the template turnover rate is improved.
本发明涉及白水泥外加剂技术领域，具体为一种白色硅酸盐水泥的复合液体早强剂，包括如下重量份数的原料，增强组分30～40份、辅助增溶稳定组分5～10份和载体50～65份，所述复合液体早强剂的总份数为100份，所述增强组分为有机盐、无机盐增强剂，所述有机盐、无机盐增强剂包括草酸钠、碳酸钠以及氟硅酸镁，所述辅助增溶稳定组为木质素磺酸盐和聚合甘油的混合物，所述木质素磺酸盐为木质素磺酸钠，所述聚合甘油为三聚甘油，本发明的复合液体外加剂，环境友好性强，制备过程简单，提高白水泥早期（3d）强度10%～15%，节约白水泥制品养护时间和提高了模板周转率。
