Problems solved by technology

[0008] A comprehensive analysis of the existing test technology found that there is no formed experimental device at present, and the experimental process is complicated to operate, and it is impossible to conduct self-healing experiments on multiple specimens at the same time, and the application of water pressure can only be carried out from top to bottom, often only Self-healing test of concrete specimens of the same shape

Abstract

The invention relates to an experimental device system for testing concrete crack self-healing ability, belonging to the field of water conservancy and civil engineering. The system can be used in the test fields of natural healing ability study of concrete, bionic self-healing study and self-healing ability study realized by adulterating special materials in a cement base. According to the experimental device system, the height of a water tank can be adjusted, and then the experimental water pressure value can be flexibly adjusted; the healing tests of multiple sets of test-pieces can be simultaneously conducted; the application of water pressure not only can be conducted from top to bottom but also can be conducted from bottom to top; the shapes of concrete test-pieces are not limited, and can be either square or cylindrical; by an observation window formed by a transparent material, the crack closure situation in the experimental process can be tracked and recorded in the whole course. According to the experimental device system, the crack self-healing ability of the concrete test-pieces can be studied from multiple angles, the structure is simple, and the operation is convenient.

Description

technical field [0001] The invention relates to an experimental device system for testing the self-healing ability of concrete cracks, belonging to the field of water conservancy and civil engineering. Ability research and other testing field applications. Background technique [0002] For the anti-seepage components of hydraulic structures, it is always worried that the damage caused by internal reaction or external influence will change the material properties or produce cracks. Cracks cause water leakage in anti-seepage components, and even gradually lead to the collapse of the entire building. The main reason for the failure of concrete structures is the expansion of micro-cracks, so repairing the expansion cracks in time can effectively slow down the failure. However, using manual repair technology not only delays the optimal repair time, but also consumes human and financial resources. The economics and effectiveness of structural repairs would be greatly improved i...
