On application of expansion admixture and compensated shrinkage concrete in super-long basement structure

The paper introduces the application of the expansion admixture and compensated shrinkage concrete in super-long basement structure,analyzes the reasons for the cracks on the super-long basement structure,illustrates the mechanism for the expansion admixture and compensated shrinkage concrete,and sums up the methods for adopting the compensation and shrinkage concrete to control the shrinkage cracks of the super-long basement structure,so as to direct the practice.
