An Evaluation of the Maturity Method (ASTM C 1074) for Use in Mass Concrete,

Abstract

Maturity parameters were determined on a mass concrete mixture according to American Society for Testing and Materials (ASTM) C 1074. Time-temperature measurements were made on two concrete placements at Red River Lock and Dam 4 for the first 40 to 60 days after placement. These data were used to predict strengths from the concrete's maturity. The placements were also cored to determine in-place strength. Strength development within the first few days of placing were reasonably well predicted by maturity, but predicted and measured strength differed widely after that. Large uncertainties in the maturity parameters were encountered. Probable causes of the large differences and the large uncertainties are discussed and recommendations made on modifications to the procedure for mass concrete.
