Concrete antifreezing agent
The invention discloses a concrete antifreezing agent which comprises the following components in parts by weight: 18-30 parts of a polycarboxylic acid-based high-performance water-reducing agent; 3-11 parts of triethanolamine; 3-10 parts of sodium acetate; 0.5-1 part of alkyl sodium benzene sulfonate; and 55-60 parts of water. The problems that an antifreezing agent prepared by compounding based on a naphthalene-based high-efficiency water-reducing agent has high mixing amount, can precipitate crystals under a low-temperature condition and has concrete durability are solved; the concrete antifreezing agent improves the construction technology of concrete under the low temperature condition, besides, promotes comprehensive and rapid development of the polycarboxylic acid water-reducing agent in China, and provides the concrete antifreezing agent.
