Water content is an important parameter deciding the strength.
A nominal mix is designed based on the ratios given in code IS:456 - 2000 and can be hand mixed on site. Nominal mixes are done for strengths up to 20MPa (i.e. M20).

The above water content may be changed for better workability keeping the w/c ratio constant.
