The performance, strength, crack resistance, freeze-thaw resistance, chloride ion content,electric flux of concrete mixture of C30 high-performance concrete are tested in four groups with different mix proportions. The effects of the different content mineral admixtures on the mechanical strength and durability of low-strength & high-performance concrete are analyzed. Based on the result of the tests and the analysis above,we draw the conclusion that the durability of low-strength and high-performance concrete is the best when the proportion of the mineral admixture content is between 40% and 50%.
