Description

[0002] Now many buildings are constructed using concrete, and cracks are the norm reflecting concrete diseases. Any damage and destruction of concrete structure first manifests as cracks in concrete, so the analysis of concrete diseases should be based on the analysis of cracks in concrete structure. Cracks in concrete structure are caused by initial defects in materials and the expansion of microcracks. Cracks in concrete can be roughly divided into two categories:

[0003] 1. Cracks caused by external load, called structural cracks, also known as load cracks; 2. Cracks caused by deformation, called non-structural cracks, also known as non-load cracks, such as cracks caused by shrinkage of concrete due to temperature changes, etc. After cracks occur, repair materials are usually used to repair cracks. Generally, the following materials are included: 1. Modified epoxy resin, modified acrylic ester, modified polyurethane and other repair glue, including supporting use of primer, repair glue and polymer grouting material, etc. Resin repair materials; this material is suitable for crack sealing or reinforcement. The specific operation can be performed by surface sealing, injection method or pressure grouting method for repair; 2.
