was equivalent to 374 lb (170 kg) of cement. One-quarter barrel of cement was then equivalent to 94 lb (43 kg), which quickly became the accepted basis for the quantity of cement in a bag or sack. Today, more than 121 million metric tons (133 million tons) of portland cement are used each year in the United States.

to 15% intergroundlimestone replacing cement clinker and to ASTM C595 in 2011 (CSA Type GUL and ASTM Type IL). • PLC have to meet the same set times and strength development as portlandcement of the same type (eg.GU = GUL; Type I = Type IL) • In addition, fewer raw materials and less energy are used to produce PLC.
