Recommended mix proportion of ingredients for grade of concrete M30 obtain from test result – From obtained test result for target strength 38.25 N/mm 2 (> 34 N/mm 2, OK) we get, Water-cement ratio = 0.38 Water content = 145 kg/m 3 (0.145 m 3) Cement content = (145/0.38) = 381.58 kg/m 3 (0.121 m 3) Superplasticizer = 7.63 kg/m 3 (0.0067 m 3)

In this case w/c = 0.4 lower by 0.10. So, the proportion of volume of coarse aggregate is increased by 0.02 (at the rate of ± 0.01 for every ± 0.05 change in water-cement ratio). For pump or worked around congested reinforcing steel required more workable concrete the coarse aggregate proportion may be reduced up to 10%. Hence,

 · Based on various lab tests, grade of concrete is presented in Mix Proportions. For example, for M30 grade, the mix proportion can be 1:1:2, where 1 is the ratio of cement, 1 is the ratio of sand and 2 is the ratio of coarse aggregate based on volume or weight of materials. Mix design M30 Grade designed as per IS 10262:2009 & IS 456:2000

Proportions for Nominal Mix Concrete As per IS 456-2000, Table 9 – NOTE: 1- General ratio of fine aggregate to coarse aggregate is 1:2, but it can be adjusted between 1:1.5 to 1:2.5 based on the grading of fine aggregate and size of coarse aggregate.
