3. A concrete self-healing mixing capsule is characterized in that: the capsule can be used for wrapping powder or water, and the gel material can be single component or double component or multi-component, inorganic or organic.

Technical Field

The invention relates to the field of building construction, and discloses a method for realizing self-healing of a concrete crack.

Background

There are problems: concrete of a basement and a roof of a building can crack, leakage can occur after the concrete cracks, later-stage leakage stoppage treatment is troublesome, damage can be caused to the structure of the concrete, the durability of a main body structure is affected, and the concrete wool capable of self-healing cannot be invented. Based on the above problems, solutions are sought.

Disclosure of Invention

At present, concrete cracks are inevitable, more or less cracks are generated, some cracks are insufficient in bearing capacity of a stress structure, the structure needs to be reinforced and reinforced, most cracks belong to non-structural cracks, once the cracks occur, rainwater and underground water erode the structure and slowly develop into through cracks, once the through cracks are formed, leakage occurs, after the later-stage plugging treatment, damage to the self structure of the concrete is troublesome, the durability of the main body structure is affected, and the self-healing concrete can not be invented. The powder in the capsule can be ultrafine concrete, or can be a material which can be mixed with water to form gel and concrete bonding and fill cracks, such as sodium silicate (powder of water glass). The capsule can be made into rough edges, after a concrete crack develops, the crack surface and the rough edges can form an intersecting line, the capsule with the rough edges is automatically torn open, and the capsule can also be made into a capsule which is slowly released when meeting water. The capsule can be used for wrapping powder and also can be used for wrapping an aqueous solution, and the quality of concrete is easily influenced by breaking the capsule during pumping and mechanical stirring. The gel material can also be single-component, double-component or multi-component, and can be inorganic or organic.

Drawings

The following description will further describe aspects of embodiments of the present invention, by taking an example of an underground concrete wall mixed with capsules having raw edges, with reference to the accompanying drawings and embodiments. The underground concrete wall mixed with the concrete self-healing mixing capsule is shown in figure 1, the detailed schematic diagram of the self-healing mixing capsule is shown in figure 2, a crack occurs in the concrete wall, the intersection line of the capsule rough edge and the crack surface is shown in figure 3, and the crack heals after the gel is hardened is shown in figure 4.

FIG. 2 is a detailed view of a self-healing mixing capsule

FIG. 3 is a schematic view showing the intersection line between the capsule raw edge and the crack surface

FIG. 4 is a schematic representation of fracture healing after gel hardening

Detailed Description

As shown in figure 2, the self-healing mixing capsule is provided with jagged rough edges at the edges, after a concrete crack develops, a crossed line is formed by the crack surface and the rough edges, the capsule with the rough edges is automatically torn open, powder in the capsule and underground water are mixed to form gel as shown in figure 3, and the crack heals as shown in figure 4 after the gel hardens.
