Repair method of concrete structure

Abstract

The invention provides a repair method of a concrete structure, and relates to the technical field of concrete. The repair method of the concrete structure comprises the steps that multiple contrast color blocks are manufactured, and the material mixing proportion of each contrast color block is recorded; the multiple contrast color blocks and the concrete to-be-repaired area are subjected to color contrasting; the contrast color block with the minimum color difference with the concrete to-be-repaired area is selected, and a repair material is blended according to the corresponding material mixing proportion; and the concrete to-be-repaired area is repaired through the repair material. Due to the fact that the contrast color blocks of different colors are used for being subjected to colorcontrasting with the concrete to-be-repaired area, the color of the repair material can be similar to the color of the concrete to-be-repaired area to the greatest extent, after repair is finished, the appearance colors of the concrete structure can tend to be consistent, and the problem of the appearance quality of the concrete structure is relieved.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a method for repairing concrete structures. Background technique [0002] Concrete is a general term for engineering composite materials that combine aggregates into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering. Concrete structures are often degraded and cracked due to environmental factors or human factors, causing water vapor to penetrate into the concrete structure. At the same time, cracks will affect the structural strength of the concrete structure. Therefore, repair materials must be injected to fill the concrete structure. strength. [0003] At present, in the process of repairing...

Problems solved by technology

[0004] However, since the color of the concrete structure will change with the influence of construction time and environmental factors, in the process of repairing, the color of the concrete structure is often different from that of the concrete structure when repaired with the original concrete material, which affects the concrete structure. appearance quality
