Sulphoaluminate cement concrete admixture
The invention discloses a sulphoaluminate cement concrete admixture, and relates to the technical field of concrete, wherein the sulphoaluminate cement concrete admixture comprises the following components in parts by mass: 150-250 parts of a water reducing type polycarboxylate superplasticizer, 0-100 parts of a slump retaining type polycarboxylate superplasticizer, 100-350 parts of boric acid, 5-30 parts of sodium gluconate and 0.1-0.5 part of an air entraining agent. The sulphoaluminate cement concrete admixture has the advantages that (1) the concrete workability of the sulphoaluminate cement can be effectively improved, the slump loss of the concrete within 1 hour and 2 hours is reduced, and the constructable time of the concrete is prolonged; (2) the preparation process of the sulphoaluminate cement concrete admixture is simple, the operation is simple, the process is reasonable, and the sulphoaluminate cement concrete admixture is beneficial to industrial production; and (3) thesulphoaluminate cement concrete admixture disclosed by the invention is an environment-friendly material and has no pollution to human bodies and the environment.
本发明公开了一种硫铝酸盐水泥混凝土外加剂，涉及混凝土技术领域，按质量份计，所述硫铝酸盐水泥混凝土外加剂包括：减水型聚羧酸减水剂150‑250份，保坍型聚羧酸减水剂0‑100份，硼酸100‑350份，葡糖糖酸钠5‑30份，引气剂0.1‑0.5份。本发明的优势在于：(1)本发明可有效提高硫铝酸盐水泥混凝的和易性好，降低混凝土1h、2h坍落度损失，增长混凝土的可施工时间；(2)本发明的硫铝酸盐水泥混凝土外加剂的制备过程简单，操作简洁，工艺合理，有利于工业化生产；(3)本发明的硫铝酸盐水泥混凝土外加剂为环境友好型材料，对人体和环境无污染。
