Self-repairing concrete structure and manufacturing method thereof

Abstract

The invention relates to a self-repairing concrete structure. The self-repairing concrete structure comprises a concrete member. A plurality of glass tubes are embedded inside a tension area of the concrete member, wherein openings of the glass tubes are sealed, and the glass tubes contain chloroprene rubber adhesives. The axial direction of the glass tubes is parallel to the tension direction of the tension area of the concrete member. The invention further provides a manufacturing method of the self-repairing concrete structure. According to the self-repairing concrete structure, the safety and long-term durability of great civil infrastructures such as high-rise buildings, bridges and nuclear power stations can be ensured, damage caused by a plurality of damage factors such as typhoon and earthquake shock is reduced, the repaired bearing capacity can be recovered to be 99%, and the service life of the concrete member is prolonged.

Description

technical field [0001] The invention relates to a self-repairing concrete structure and a manufacturing method thereof, belonging to the field of self-repairing concrete and similar building materials. Background technique [0002] Due to the long-term use of concrete structures and the influence of the surrounding complex environment, small cracks and local damage will inevitably occur. The light ones will reduce the service life of the structure, and the severe ones will endanger the safety of the structure. Over the years, people have studied and improved raw materials, mix ratios, admixtures, manufacturing processes, pouring and tamping methods, and curing processes, and have achieved great results, but these methods have not fundamentally changed the performance weaknesses of concrete. . Therefore, the timely and effective repair of cracks and damages in service structures has become our main concern. Due to macroscopic damage caused by earthquakes, wind loads, shock ...

AI Technical Summary

Problems solved by technology

However, in the actual concrete engineering structure, there are many tiny cracks, such as micro-cracks in the matrix, etc. These microscopic damages may not be detected due to the limitation of detection technology.

Therefore, it becomes very difficult or even impossible to repair these undetectable cracks and damages, but if these cracks or damages cannot be repaired in a timely and effective manner, it will not only affect the normal performance of the structure and shorten the service life. life, and may cause macroscopic cracks and cause brittle fracture of the structure, resulting in serious catastrophic accidents
