Advances in Constructional Engineering

Concrete cracks are a common issue in construction engineering, significantly affecting structural stability and service life. This paper explores the primary causes of crack formation, analyzes the characteristics and hazards of different crack types, and proposes corresponding control and repair techniques. The occurrence of concrete cracks is closely related to multiple factors including temperature changes, improper construction methods, and load effects. Effective measures such as rational design, enhanced construction management, selection of appropriate materials, and post-construction curing can significantly reduce crack incidence. For existing cracks, repair methods include grouting, reinforcement, and compensation. The effectiveness of concrete crack control and treatment is crucial for the long-term safety of construction projects.
