With the development of society, high-strength and large volume concrete is widely used in the foundation slabs and bridge structures of super high-rise buildings.
High strength and large volume concrete not only needs to meet strength standards, but also needs to consider controlling the temperature difference between the inside and outside of the concrete, reducing hydration heat, and preventing concrete cracking caused by excessive temperature differences.
High strength and large volume concrete, especially concrete with a strength exceeding C50, has a high frequency of cracking problems.
Therefore, solving the problem of concrete cracking is currently the focus of crack resistance research.
