Restrain Effect of Expansive Admixture in Concrete Members

Abstract:

This paper evaluated the restrain effect to cracks in the concrete members containing expansive admixture addition. An experimental study modeling the slab of the field bridge is performed. The free strain, the actual strain of specimens with or without expansive admixture and steel bars is measured. Based on the experimental results, the internal restrain effect and steel restrain effect to cracks are calculated as approximately 0.35 and 0.2~0.3 respectively.
