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.
