Abstract

The invention discloses an environment-friendly cement expanding agent and belongs to the technical field of concrete addition agents. The expanding agent is prepared from, by weight, 15-20 parts of acetyl trioctyl citrate, 1-3 parts of phenethyl cumenyl phenol polyoxyethylene ether, 5-15 parts of alunite, 2-6 parts of aluminum-oxygen clinker, 10-30 parts of calcium sulphoaluminate, 4-12 parts of aluminum slag, 1-5 parts of calcium carbonate powder, 4-12 parts of nanometer aluminum titanate fibers and 8-16 parts of pitchstone ore sand. The environment-friendly cement expanding agent is high in expansion rate, low in alkalinity content and capable of improving the concrete performance, concrete cracking is prevented, meanwhile, leakage is reduced, the strength is improved, the price is low, the production process is simple, the cost is low, and the expanding agent is suitable for large-scale production.

Description

technical field [0001] The invention relates to an environment-friendly concrete expansion agent, which belongs to the technical field of concrete additives. 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] The purpose of the invention is to make up for the deficiencies of the prior art and provide an environment-friendly concrete expansion agent. The env...
