The sand has a moisture content of 3.3% andan absorption of 4.7%. The gravel has a moisture content of 3.6% and an absorptionof 4.5%. Since water absorbed in the aggregate does not react with the cement or improve the workability of the plastic concrete, what is the water–cement ratio of this mix according to the American Concrete Institute’s weight mix design method?
