Dry powder cement admixture as well as preparation method and application thereof
The invention relates to a dry powder cement admixture as well as a preparation method and application thereof. The catalyst comprises the following components in percentage by mass: 4%-8% of sodium thiocyanate, 8%-16% of sodium thiosulfate, 0.4%-1.2% of organic alcohol amine, 16%-32% of macromolecular resin and 54%-68% of a carrier, the polymer resin comprises a sulfonic acid group, an acrylic acid group, an amide group and graphene oxide. The technical problem to be solved by the invention is how to provide the dry powdery cement admixture, so that the dry powdery cement admixture has better performance when being matched with a concrete system of a downstream supplier for use. The strength of the concrete can still reach a better level after the addition proportion of the cementing material is greatly reduced during concrete preparation, and the cost is saved, so that the concrete is more practical.
本发明是关于一种干粉状水泥掺合料及其制备方法和应用。以质量百分含量计，其包括：硫氰酸钠4％～8％，硫代硫酸钠8％～16％，有机醇胺0.4～1.2％，高分子树脂16～32％，载体54～68％；高分子树脂中包含磺酸基团、丙烯酸基团、酰胺基团和氧化石墨烯。本发明所要解决的技术问题是如何提供一种干粉状水泥掺合料，使其与下游供应商的混凝土体系配合使用时具有较好的性能；在较多地降低混凝土配制时胶凝材料的添加比例后混凝土的强度仍能达到较好的水平，成本节约，从而更加适于实用。
