Permeable crystallization type self-repairing concrete structure and manufacturing method thereof

Abstract

The invention discloses a permeable crystallization type self-repairing concrete structure. The permeable crystallization type self-repairing concrete structure comprises a concrete component. Permeable crystallization material particles and sodium silicate repairing agent particles are evenly arranged in the concrete component, and the sodium silicate repairing agent particles are of micro-capsule structures. The invention further provides a manufacturing method of the permeable crystallization type self-repairing concrete structure. The mechanical performance and the the waterproof anti-permeability performance of the concrete structure can be improved, the concrete structure has the damage self-repairing capacity, and therefore the safety, the durability and the economical efficiency ofthe concrete structure are improved.

Description

technical field [0001] The invention relates to a permeable crystalline self-repairing concrete structure and a manufacturing method thereof, including concrete components, and belongs to the field of self-repairing concrete and similar building materials. Background technique [0002] During the normal service process of concrete, due to factors such as environment and fatigue damage, cracks will inevitably occur. These cracks provide a channel for harmful substances from the outside to enter the interior of the concrete, thereby accelerating the corrosion of internal steel bars and reducing the safety of concrete structures. and durability. For the fully developed macroscopic cracks, we can easily identify them with the naked eye, and use traditional methods, such as structural reinforcement, grouting, and filling methods, to repair them later; , it is difficult to be detected timely and accurately. At this time, the traditional crack repair methods cannot achieve the rep...

Problems solved by technology

For the fully developed macroscopic cracks, we can easily identify them with the naked eye, and use traditional methods, such as structural reinforcement, grouting, and filling methods, to repair them later; , it is difficult to be detected timely and accurately. At this time, the traditional crack repair methods cannot achieve the repair effect, and the microscopic cracks that cannot be repaired in time will not only affect the normal performance of the structure and shorten the service life, but may also develop further. For macro cracks and lead to brittle fracture of the structure, resulting in serious catastrophic accidents

More importantly, the cost of traditional crack repair methods is very high, consuming a lot of manpower and material resources
