Investigation of Cement-Replacement Materials. Report 13. Use of Water-Reducing and Water-Reducing Retarding Admixtures in Mass Concrete
The purposes of the investigation were to evaluate the effects of certain water-reducing admixtures on the workability, heat generation, strength, cost, and other characteristics of mass concrete mixtures containing large amounts of pozzolan and small amounts of portland cement. Four chemical admixtures were tested for compliance with Corps of Engineers specifications and three were selected for use in the tests of mass concrete. Mass concrete mixtures were proportioned with and without pozzolans. Results of tests on workability, compressive strength, and heat generation, and cost comparison were used in evaluating the performance of chemical admixtures in mass concrete. (Author)
