Concrete composite anti-freezing agent and preparation method thereof
The invention discloses a concrete composite anti-freezing agent and a preparation method thereof. The concrete composite anti-freezing agent comprises the following raw materials by mass: 15-30 parts of a water reducing component, 10-50 parts of an anti-freezing component, 1-3 parts of an early strength component, 0.1-0.3 part of an air entraining component, and 30-50 parts of water. The obtained composite anti-freezing agent is free of pungent smell; the doping amount in a cementing material is small; the composite anti-freezing agent is free ofchlorine and low in alkali, and has no corrosion effect on reinforced concrete; no flocculent substance overflows after the anti-freezing agent solution is stored at the temperature of -20 DEG C for 7 days; and the compressive strength ratio of the concrete composite anti-freezing agent at the temperature of -20 DEG C is obviously higher than the set requirement of -15 DEG C specified in JC457-2004.
本发明公开了一种混凝土复合防冻剂及其制备方法，按质量份，其原料包括以下组分：减水组分15‑30份、防冻组分10‑50份、早强组分1‑3份、引气组分0.1‑0.3份、水30‑50份。本发明得到的复合防冻剂无刺激性气味；在胶凝材料中掺入量较少；无氯、低碱对钢筋混凝土无锈蚀作用；防冻剂溶液‑20℃存储7天无絮凝状物质溢出；‑20℃下混凝土复合防冻剂的抗压强度比明显高于JC457‑2004中规定的‑15℃的设定要求。
