On the generation and control of concrete cracks
Guide: Concrete plays an important role in modern engineering construction. Today, concrete cracks are more common, and cracks are almost everywhere in bridge engineering. In mass concrete, temperature stress and temperature control are of great significance. There are many reasons for cracks in concrete, mainly including changes in temperature and humidity, brittleness and unevenness of concrete, unreasonable structure, unqualified raw materials (such as alkali aggregate reaction), deformation of formwork, uneven settlement of foundation, etc.
