| Abstract: | The Fujian Mianhuatan Hydropower Development Co. Ltd. tested and studied the properties of the artificial sand concrete with different contents of stone powder, such as mix proportion, compressive strength, ultimate elongation value, tensile elastic modulus, impermeability and drying shrinkage. The test and study results showed that the artificial sand with proper content of stone powder can improve the performance of concrete and the concrete with 16 percent stone powder content has the best comprehensive performance which has applied to the normal concrete in the Mianhuatan Hydropower Station. |
