Concrete crack self-healing mixing capsule

Abstract

The invention disclsoes a concrete crack self-healing mixing capsule. According to the concrete mixing capsule, when a crack is generated, the capsule in concrete can be automatically torn along with the development of the crack, powder in the capsule can form concrete-philic gel after encountering water to fill the crack, and the crack is bonded off after the gel is hardened, so that the purpose of self-healing of the concrete is achieved. The capsule can be made into a rough edge, after a concrete crack is developed, a crack surface and the rough edge can form an intersection line, the capsule with the rough edge is automatically torn, and the capsule can also be made into a capsule which is slowly released when meeting water.

Description

technical field [0001] The invention relates to the field of building construction, how to realize self-healing of concrete cracks. Background technique [0002] Existing problems: the concrete in the basement and roof of the building will crack, and leakage will occur after cracking. The later plugging treatment is troublesome and will cause damage to the concrete structure itself and affect the durability of the main structure. Can we invent a self-healing method? Composite concrete. Based on the above problems, find a solution. Contents of the invention [0003] At present, concrete cracking is inevitable, more or less there will be cracks, and some cracks are due to insufficient bearing capacity reserves of the stressed structure, and the structure needs to be reinforced. Most of the cracks are non-structural cracks. Once cracks occur, Rainwater and groundwater will erode the structure and slowly develop into a through joint. Once a through joint is formed, leakage w...
