Abstract:Based on the problem of floor cracks in a cast-in-place concrete structure shortly after roof structural capping, the detection process and method of floor cracks were introduced, and the results of each test parameter were scientifically discriminated, and then the factors affecting the crack generation were analyzed by using the effective parameters of the test. Corresponding treatment methods were put forward for various types of cracks in cracked floor slabs, and the comprehensive reinforcement method was adopted for the structure combined with the causes of cracks and the present situation of bearing capacity. Through the systematic diagnosis and treatment of on-site inspection, data analysis, cause assessment and treatment reinforcement of the project, it provided a reference for scientific detection, assessment and treatment of similar floor crack problems in the future.

Keywords:cast-in-place concrete floor; crack; detection assessment; reinforcement
