Abstract : Pertinent physical properties of two interior mass concrete mixtures were determined and used as input to a finite-element computer code for prediction of temperature rise in mass concrete. Potential tensile strains were computed based on the temperature history and coefficient of thermal expansion. Comparison of these computed strains with the results of the ultimate strain capacity tests indicates where potentially critical strains could occur if movement were restrained. Information obtained in this investigation provides a basis for the establishment of some of the temperature and construction control plans aimed toward minimizing thermal cracking.
