Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For e.g., 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.
So modifications and changes are needed in trial mix 1 to get the desired workability. Concrete Trial Mix 2: To increase the workability of concrete mix from 25 mm to 50-75 mm an increase in water content by +3% is to be made. The corrected water content for mix = 191.6 x 1.03 = 197.4 kg.
