Abstract:
A comparison was made between the strength-maturity relations of concrete cylinders cured outdoors and cylinders cured in a laboratory. It was found that when early age (assumed as 48 hr) temperatures of the outdoor-cured and laboratory-cured cylinders were similar, the strength-maturity relations were similar despite temperature fluctua-tions experienced by the outdoor-cured specimens. The relations were dissimilar when their early age temperatures differed. Another series of testsfurther investigated and confirmed the importance of early age temperature on the strength-maturity relation.
