Sand Equivalents - Quality in California

Apr 30, 2011· So if your sample has a 90 sand equivalent that means that 90% of the sample was good material and 10% was detrimental. If you have a 40 sand equivalent that means that 40% of the sample was good material and 60% was detrimental. Many materials such as concrete sands will have high SEs, in the 80s or 90s but it is very rare to see a 100 SE.

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.
