# 2500 Psi Concrete Mix Ratio

what is the concrete ratio for 3000 psi? - quora,nominal mix to obtain m20(3000 psi) grade concrete is 1:1.5:3(cement:sand:coarse aggregate), by volume. but normally you will get the strength even when you use 1:2:4 mix. the main consideration in any concrete construction is to get durability and water tightness in addition to strength..what concrete mix to use for a driveway | concrete questions,the ideal concrete mix to use for constructing a driveway should have at least a 4,000 psi compressive strength, a water-cement ratio of 0.50, aggregates no larger than 1.
