Abstract

The invention discloses an auxiliary agent for reducing the dilution rate of concrete. The auxiliary agent is prepared from the following raw materials in parts by weight: 20-40 parts of fly ash, 10-20 parts of ammonium persulfate, 30-40 parts of polyethylene glycol methacrylate, 1-2 parts of mercaptoethanol, 3-5 parts of boric acid, 20-35 parts of polyethylene glycol, 10-16 parts of calcium silicate, 10-30 parts of sodium hydroxide, 20-40 parts of air entraining agent, 15-30 parts of retarder, 8-16 parts of concrete shrinkage reducing agent, 12-26 parts of water reducer, 13-21 parts of an expanding agent, 12-18 parts of an accelerator and a proper amount of water. The invention relates to the technical field of concrete auxiliary materials, and by using fly ash, ammonium persulfate, polyethylene glycol methacrylate, mercaptoethanol, boric acid, polyethylene glycol, calcium silicate, sodium hydroxide, an air entraining agent, a retarder, a concrete shrinkage reducing agent, a water reducing agent, an expanding agent, an accelerator and other materials, the bleeding rate and the dilution rate of concrete can be effectively reduced, and the use strength of concrete can be improved.

Description

technical field [0001] The invention relates to the technical field of concrete auxiliary materials, in particular to an auxiliary agent for reducing the separation rate of concrete. Background technique [0002] The separation of concrete is the phenomenon that the cohesion between the constituent materials of the concrete mixture is not enough to resist the sinking of the coarse aggregate, and the components of the concrete mixture are separated from each other, resulting in uneven internal composition and structure. It usually shows that the coarse aggregate and the mortar are separated from each other, for example, the dense particles are deposited at the bottom of the mixture, or the coarse aggregate is completely separated from the mixture; [0003] When the separation rate of concrete is high, the strength of concrete is likely to drop significantly, seriously affecting the bearing capacity of the concrete structure, destroying the safety performance of the structure,...
