Very little has been published on procedures for proportioning mass concrete mixtures containing aggregates above 3 inches in size. The procedures currently in use by organizations deeply involved with mass concrete require a high degree of experience. The procedure described in this paper removes the necessity for this experience although an individual having knowledge of acceptable mass concrete workability should be available to evaluate the trial batch results and initial adjustments. The procedure described is intended primarily for proportioning concrete mixtures using aggregates above 3 inches in size but could be used to proportion concretes using smaller maximum size aggregate (1 and 2 inches).
