Waterproof anti-crack concrete admixture and preparation method thereof
The invention discloses a waterproof anti-crack concrete admixture and a preparation method thereof, and belongs to the technical field of building material admixtures. The waterproof anti-crack concrete admixture comprises 20 to 30% of a water reducing agent, 10 to 15% of sodium gluconate, 0.05 to 0.3% of an air entraining agent, 0.05 to 2% of an acrylate copolymer, 0.01 to 1.5% of a sodium sulfonate polymer, 0.01 to 0.5% of cellulose ether, 0.01 to 0.5% of polypropylene fiber, 0.01 to 0.5% of a water repellent and the balance of water. According to the novel waterproof anti-crack concrete admixture disclosed by the invention, under the combined action of all the raw materials, the anti-freezing and anti-permeability properties of concrete are greatly improved, the durability of the concrete is improved, and the service life of the concrete is prolonged. Meanwhile, the novel waterproof anti-crack concrete admixture is simple and convenient in preparation method, low in cost and remarkable in economic benefit and social benefit.
本发明公开一种防水抗裂混凝土外加剂及其制备方法，属于建筑材料外加剂技术领域。本发明防水抗裂混凝土外加剂包括减水剂20‑30％、葡萄糖酸钠10‑15％、引气剂0.05‑0.3％、丙烯酸酯共聚物0.05‑2％、磺酸钠聚合物0.01‑1.5％、纤维素醚0.01‑0.5％、聚丙烯纤维0.01‑0.5％、憎水剂0.01‑0.5％，余量为水。本发明的新型防水抗裂混凝土外加剂，在各原料共同作用下，大大提高了混凝土的防冻抗渗性、提高了混凝土的耐久性，提高了混凝土的使用寿命。同时，本发明的新型防水抗裂混凝土外加剂，制备方法简单方便，成本低，经济效益和社会效益显著。
