The invention discloses a composite concrete expansive agent, and belongs to the technical field of concrete additives. The composite concrete expansive agent is prepared from, by weight, 4-16 parts of 3-aminopropyltrimethoxysilane, 5-10 parts of sulfamic acid, 3-10 parts of alunite, 1-6 parts of aluminum oxygen chamotte, 2-10 parts of calcium sulphoaluminate, 4-12 parts of aluminum slag, 1-5 parts of calcium carbonate powder, 4-12 parts of nanometer aluminum titanate fiber and 2-10 parts of phenethyl cumenyl phenol ethoxylate. The composite concrete expansive agent is high in expansion rate, low in alkali content, low in price, simple in production process, low in cost, suitable for large-scale production and capable of improving performance of concrete, preventing concrete from cracking, reducing leakage and improving strength.
