C20 Concrete Mix Ratio Water

types of concrete grade and their ratio as per british,nominal mix ratio of c20 concrete grade is 1 : 1.5 : 3, in which one part is portland stone cement mixed with 1.5 part of fine aggregate/sand and 3 part of coarse aggregate with required quantity of water to reach compressive strength 20 newton per square millimetre.determination of appropriate mix ratios for concrete,1:2:4 and 1:1.5:3 mix ratios respectively. to produce concrete with strength class c20/25 which is the minimum concrete strength class recommended for the construction of the load-bearing building structural members using the 1:2:4 mix ratio, portland-limestone cement.
