| Abstract: | By simulating the sulfate corrosion condition of concrete structure widely used in hydraulic projects and water transportation engineering,we study the compressive strength and wear-resisting property of self-compacting concrete based on the tests.We also analyze the internal mechanism of performance changes of self-compacting concrete by pore structure analysis method.The results show that its pore structure is greatly improved.Therefore,the self-compacting concrete has good durability in sulfate erosion condition. |
| Keywords: | self-compacting concrete sulfate attack durability pore structure analysis |
