Water-to-Cement Ratio and Aggregate Moisture Corrections

May 28, 2010· By Adam D. Neuwald. Two of the most commonly specified requirements for concrete used in the manufactured concrete products industry are the design compressive strength (f'' c) and the maximum water-to-cement ratio (w/c).These two values are inversely related, which means that as the water-to-cement ratio increases, the compressive strength decreases.
