Concrete performance improver and preparation method thereof
The invention discloses a concrete performance improver and a preparation method thereof, and belongs to the technical field of concrete admixtures. The concrete performance improver effectively solves the contradiction between the concrete flowability, the flowability maintenance and the concrete segregation and bleeding. The concrete performance improver comprises, by weight, 1-3 parts of triethylene glycol, 1-3 parts of diethylene glycol, 5-8 parts of an inorganic dispersion component, 0.1-1 part of sodium ethylenediamine tetramethylene phosphonate, 3-8 parts of modified starch, 0.1-0.5 part of diethanolisopropanolamine, 0.001-0.01 part of an air entraining agent, 1-2 parts of manganese pyrophosphate and 80-100 parts of zeolite powder. The concrete performance improver can be used for improving the performance of concrete.
