Large volume concrete refers to concrete components with a single large volume, generally referring to concrete with a single volume of more than 1 cubic meter.
Large volume concrete is widely used in important infrastructure projects such as water conservancy hubs, large foundations, and bridges.
Compared with ordinary concrete, large volume concrete has significant temperature stress and shrinkage problems due to its larger block size, which can easily cause cracks and affect the quality and service life of the project.
Widely used in dams and ship locks in water conservancy and hydropower engineering, foundation slabs and transfer layers in industrial and civil buildings, and large bridge piers and abutments in bridge engineering.
Therefore, studying the influencing factors and effective preventive measures of cracks in large volume concrete is of great significance for improving the quality of large volume concrete engineering.
