High-performance concrete expanding agent

Abstract

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.

Description

technical field [0001] The invention relates to a high-performance concrete expansion agent. Background technique [0002] Excessive alkali content in concrete will trigger alkali-aggregate reaction and cause structural damage, which is an important reason affecting the durability of concrete. Concrete expansion agent does not contain sodium salt and should not cause alkali-aggregate reaction in concrete. And the durability is good, the expansion performance is stable, and the strength continues to rise. Ordinary concrete often leaks due to shrinkage and cracking, which reduces its use function and durability. But there are various shortcomings in the expansion agent on the market, can't satisfy people's use requirement. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a high-performance concrete expansion agent, which can improve the performance of concrete, prevent...
