The commonly assumed density of 3150 kg/m 3 (3.15 g/cm 3) for portland cement [ 4] will not be correct when limestone is interground into the cement. Neither ASTM C150 nor ASTM C595 requires the density to be reported or measured.

Predicting the 28-day strength of portland cement

A preliminary investigation into the possible use of concrete nuclear densities as a substitute for 28-day concrete specifications is reported. During the investigation five variables (slump, entrained air, cylinder strength, core strength and nuclear density) were evaluated which indicated that there existed a high correlation between cylinder strength, core strength and nuclear density.
