### Water to Cement Ratioand Aggregate Moisture Corrections

May 28, 2010· By Adam D. Neuwald. Two of the most commonly specified requirements forconcreteused in the manufacturedconcreteproducts industry are the designcompressive strength(f’ c) and the maximumwater-to-cement ratio(w/c).These two values are inversely related, which means that as thewater-to-cement ratioincreases, thecompressive strengthdecreases.
