High-performance concrete expanding agent
The invention discloses a high-performance concrete expanding agent. The high-performance concrete expanding agent is prepared from 6-13 parts by weight of an accelerator, 8-14 parts by weight of diethylenetriamine, 6-8 parts by weight of triethanolamine, 7-9 parts by weight of salicylic acid, 6-10 parts by weight of ferrous sulfate, 5-9 parts by weight of carboxymethylcellulose, 5-7 parts by weight of carragheenan, 3-8 parts by weight of cellulose acetate butyrate, 7-11 parts by weight of acetyl trioctyl citrate, 5-8 parts by weight of polyoxyethylene phenethylcumenylphenol ether, 8-15 parts by weight of aluminum ore and 2-8 parts by weight of lime. The high-performance concrete expanding agent can improve concrete performances, prevent concrete cracking, reduce seepage and improve strength.
