Crystal structure self-healing grouting method

Abstract

The invention belongs to the technical field of construction engineering structure reinforcement, and particularly relates to a crystal structure self-healing grouting method. Crystalline materials are added into 60 DEG C-80 DEG C warm water to be evenly mixed to form a saturated solution, grouting materials are additionally added to be mixed and stirred according to the ratio of grouting materialto water given by instructions of the grouting materials, stirring is carried out to a normal temperature status, and grouting is carried out based on an existing grouting method after the crystal materials crystallize fully. The crystal materials are any crystal material which is soluble in water, does not react with cement and has the effect of cooling and crystallization. According to the crystal structure self-healing grouting method, an original grouting reinforcement method is improved, lacks of the original method is supplemented, and a groundbreaking supplement is achieved to an existing reinforcement method; and according to the technical scheme, the grouting materials are adopted by an existing traditional reinforcement, but a construction method is improved, so that the concrete achieves the effect of self-healing, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of building engineering structure reinforcement, and in particular relates to a crystal crystallization self-healing grouting method. Background technique [0002] Since some buildings, such as bridge piers, road surfaces, frame columns, frame beams and other structural components, cracks occur when they are damaged, they need to be reinforced to prolong their service life. The formation of these cracks has persistence and continuity over time. When cracks occur, the original reinforcement methods generally use high-strength concrete or grouting materials or high-strength cement. However, due to the high strength of these materials , as the strength increases, it becomes brittle instead, so that after grouting the original cracks, as time goes on, the original cracks of these stressed members will continue to expand after being strengthened for a period of time.
