Background

Concrete is called concrete for short, and refers to a general name of engineering composite materials formed by cementing aggregate into a whole by cementing materials. The concrete is generally artificial stone which is prepared by taking cement as a main cementing material, adding water, sand and stones, adding chemical additives and mineral admixtures if necessary, mixing according to a proper proportion, uniformly stirring, densely molding, curing and hardening. The concrete strength grade is divided into a cubic compressive strength standard value, and the Chinese common concrete strength grade is divided into 14 grades: c15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75 and C80.

The large-scale public building concrete member that uses at present such as roof beam, board, column and building fitment fittings is the building member made in advance in the factory with concrete as the basic material, because of various reasons such as different technical strength of each factory, the mix proportion is unreasonable, etc., in the course of construction, cause the concrete to be apt to appear the colour difference after pouring the shaping to be great, local defect, concrete look and feel shaping is bad under the influence of factors such as environmental condition, physics, chemistry, etc., this makes the reinforcement of the concrete member all need the repair material; in the traditional concrete repairing material in the market, for example, patent document with application number of CN2020102982359 discloses a concrete defect repairing material and a preparation process thereof, the material takes portland cement, quartz sand, gypsum powder and fly ash as main raw materials, polymer rubber powder and various auxiliaries are added, and the used raw materials are various, so that the preparation process is long in period, time and labor are consumed, the impression quality is poor, and the construction quality is influenced to a great extent.
