[0002] Adding expansion agents to concrete to make shrinkage-compensating concrete is one of the most commonly used measures in engineering to inhibit concrete shrinkage and deformation from a material perspective. It is not only widely used in reinforced concrete projects with high requirements for crack resistance and anti-seepage, such as tunnels, bridges, and underground spaces, but also in filling concrete projects with high requirements for volume stability, such as steel tube concrete arch bridges and super-high-rise structure steel tube columns.
