Concrete Mix Design As Per Indian Standard Code , For eg, a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate The proportions are either by volume or by mass

Hence for higher grades of concrete (M40 and higher) it is advantageous to use lower maximum size of aggregate to prevent bond failure Grading of coarse aggregate: The coarse aggregate grading limits are given in IS 383 – 1970 – table 2, Clause 41 and 42 for single size ,
