For the construction of hydropower stations, mechanical performance of concrete is tested by sample concrete made by actual graded artificial sand with high content of powder. The purpose is to determine proper powder content in artificial sand and the effects of different samples on concrete performance, and their correlation are analyzed, based on which optimized powder content and size_influence conversion factors are recommended. The study results are of reference value in project construction and the modification of relative specifications.
