tion of compressive strength. Because of the lesser height to diameter ratio (1.15) of the cylinders, the compressive strength determined by Method A will normally be greater than that for Method B. 4.2 Method B, because of the greater height to diameter ratio (2.00), gives a better measure of compressive strength
