Abstract
The invention discloses a concrete slump retaining agent, consisting of the following materials in parts by weight: 35-50 parts of prenyl polyoxyethylene ether, 12-18 parts of maleic anhydride, 16-18 parts of acrylamide, 4-8 parts of ammonium persulfate and 55-65 parts of water. The concrete slump retaining agent disclosed by the invention is simple in preparation process, and particularly the concrete slump retaining agent has very good slump retaining capacity for cement which is poor in adaptability or has sand problem; and simultaneously, the concrete slump retaining agent can avoid separation or bleeding. The concrete slump retaining agent is applicable to occasions on which a conventional retarder or slump retaining agent does not work.
Description
Technical field
The present invention relates to a kind of concrete slump retaining agent.
Background technology
Slump retaining agent is the admixture that can keep concrete slump not lose fast.Traditional slump retaining agent, prepare more complicated, and due to multiplex to hazardous and noxious substances, operating process is had relatively high expectations.
Summary of the invention
Object of the present invention is exactly for above-mentioned defect of the prior art, provides that preparation is simple, toxicity is little, adapts to the concrete slump retaining agent of various working environments.
To achieve these goals, technical scheme provided by the invention is: a kind of concrete slump retaining agent, is comprised of the following material according to weight part meter: prenyl polyoxyethylene ether 35-50 part, maleic anhydride 12-18 part, acryloyl ammonium 16-18 part, ammonium persulphate 4-8 part, water 55-65 part.
Further, above-mentioned a kind of concrete slump retaining agent, is characterized in that, the following material according to weight part meter, consists of: 45 parts of prenyl polyoxyethylene ethers, 16 parts of maleic anhydrides, 17 parts of acryloyl ammoniums, 6 parts of ammonium persulphates, 60 parts, water.
Beneficial effect of the present invention is: a kind of concrete slump retaining agent provided by the invention, preparation technology is simple, especially bad for cement adaptability, or sandstone has problem, has extraordinary slump save power, avoids segregation or bleeding simultaneously.Solve and use conventional retardant or the insurmountable occasion of slump retaining agent.
