Abstract

The invention discloses a concrete anti-cracking reinforced self-repairing material and a preparation method and application thereof, and relates to the technical field of building materials. The concrete anti-cracking reinforced self-repairing material is prepared from the following raw materials in parts by weight: 40 to 60 parts of dense component, 10 to 30 parts of water storing component, 10 to 20 parts of plastifying component, 2 to 8 parts of complexing component, and 4 to 20 parts of thickening and reinforcing component. By adopting the concrete anti-cracking reinforced self-repairing material, the crack resistance of a substrate can be improved, micro-cracks or micro-damages which are not greater than 0.4mm in a concrete hardened body due to various causes can be repaired continuously, and continuous increase in the strength of the substrate after repairing of the cracks can be facilitated.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a concrete anti-cracking reinforced self-repairing material, a preparation method and an application. Background technique [0002] Concrete is the largest and most widely used building material in the world today, but its brittle nature makes it poor in crack resistance, and micro-cracks are easily generated during construction or long-term use. The existence and development of these cracks will inevitably affect the performance of concrete structures and reduce the durability and service life of concrete. [0003] The traditional method of using repair materials to repair concrete macro cracks not only increases the number of repeated constructions, but also increases the cost (repair materials are expensive). It is easy to break and the repair effect is not good. In the actual concrete engineering structure, many tiny cracks occur inside the structure. If these mi...
