FIFTY-YEAR PROPERTIES OF CONCRETE MADE IN 1937

Three long-time concrete test programs were started at the University of Wisconsin-Madison in 1910 (Series B) and 1937 (Series C). Previous reports were published in the ACI Journal in 1931, 1943, 1961, and 1975. The 1937 program required 480 cylinders of 4 x 6 x 24 in. Compressive strength, unit weight, and volume changes up to 50 years are given. In addition, transverse strength and static and dynamic moduli of elasticity at 50 years are given. Variables included cement type, mix proportions, consistency, and methods of placement. All speciimens made in 1937 were cured outdoors after a 28-day moist-curing period. Generally, compressive strength at 50 years showed little change from the strength at 10 years.
