Methods of Proportioning Cement, Sand and Aggregates in Concrete
According to Abram's Law water-cement law, lesser the water-cement ratio in a workable mix greater will be the strength. If water cement ratio is less than 0.4 to 0.5, complete hydration will not be secured. Some practical values of water cement ratio for structure reinforced concrete 0.45 for 1 : 1 : 2 concrete; 0.5 for 1 : 1.5 : 3 concrete
