The invention relates to a special additive for self-compacting concretes for concrete pouring in closed space. The special additive can be used for preparation of various self-compacting concretes and is applicable to preparation of high-flowability concretes, pouring in closed space and various special-structured buildings. The special additive is prepared from, by mass percent, 5-10 of a polycarboxylate superplasticizer, 30-50 of polycarboxylic acid, 10-20 of a viscosity modifier, 1-3 of weepage inhibitor, 0.1-0.3 of an antifoaming agent, 1-3 of a retarder and 17-47 of water. The special additive for the self-compacting concretes for concrete pouring in the closed space has advantages that concrete workability can be improved remarkably, concrete slump retaining time is prolonged, weepage and laitance layers are avoided after concrete pouring, and construction requirements of the self-compacting concretes are met.
