Experiments are conducted for the properties of C25 hydraulic self-compacting concrete, such as working performance, mechanical performance, dry shrinkage performance, deformation performance of its volume and anti-crack-ing ability, and the application effect is analyzed in combination with the engineering practice of Yunnan Longkaikou Hy-dropower Station. The results show that the use of self-compacting concrete with low strength grade of C25 can effectively improve the durability of hydraulic concrete structure, at the same time, the working performance and mechanical proper-ties of C25 hydraulic self-compacting concrete can meet the requirement of engineering design.
