Water-to-Cement Ratio and Aggregate Moisture Corrections
Water-to-Cement Ratio and Aggregate Moisture Corrections

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 decreas...
