The Bureau of Indian Standards has drawn up curves (Fig 11.2) which shows a correlation
between the water-cement ratio and the 28-days cube compressive strength of concrete made
from cements of different grades/strengths, tested according to IS: 4031–1988, and included in
IS: 10262–1982, Recommended Guidelines for Concrete Mix Design. These curves can be used
for making trial mixes as recommended in IS: 10262–1982.
