High and ultrahigh strength concrete viscosity reducer, preparation method of high and ultrahigh strength concrete viscosity reducer and application of high and ultrahigh strength concrete viscosity reducer
The invention discloses a high and ultrahigh strength concrete viscosity reducer. The high and ultrahigh strength concrete viscosity reducer contains the following substances by mass percent: 0.5 to 5 percent of nano particles, 2 to 20 percent of sulfate, 1 to 4 percent of carbonate, 0.1 to 2 percent of functional additive and the balance of water. The viscosity reducer, which is 0.1 to 0.5 percent of the mass of a binding material, is doped into high strength or ultrahigh strength concrete, the viscosity of the concrete can be reduced by more than 10 to 30 percent, the peaceability of the concrete can be remarkably improved, and the problems that the high strength or ultrahigh strength concrete is high in viscosity and difficult to construct can be effectively solved. In addition, the viscosity reducer also can improve the mechanical property and durability of the concrete. The viscosity reducer is also applicable to a mortar system with low water-binder ratio.
