Optimization Study of Expansive Agents of Shrinkage-Compensating Concrete

Abstract:

Article Preview

Using 6% HCSA, HEA and CSA equivalent replacement Slag Portland Cement add into the normal concrete, the compressive strength, splitting tensile strength and flexural strength at the age of 3d, 7d and 28d are researched. It is concluded that reinforcing effect of the three expensive agents are in order CSA, HEA and HCSA form the view of mechanics , expansive agents increase the bonding force between coarse aggregate and slurry, alleviate the development speed of cracks and increase the destruction deformability of concrete.
