Abstract:
A discussion of the effect of purposefully entrained air on the properties of concrete. Factors which affect the entrainment of air in concrete such as cement, sand, and mix temperature are discussed. Strength reductions to be expected and suggested air contents as related to maximum size aggregate are shown.

Presents basic principles of proportioning shrinkage compensating concrete mixtures using currently available expansive cements and relates them to proportioning mixtures using Type I cement. Properties which are common to all expansive cements and their differences are discussed. Conditions under which slump loss may occur when using some expansive cements are reviewed and methods for adjusting mixing water to compensate are given. Recommendations for the use of admixtures are made and importance of proper curing and adeqate internal restraint are discussed briefly.

The paper describes the proportioning of the concrete mix ingredients required when a chemical admixture is used. Generally, the chemical admixture affects the water content, the air content, and the handling characteristics of the concrete. Since the yield of concrete would be affected, several methods of adjusting the mix ingredients are described.

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).

Shu-t'ien Li and V. Ramakrishnan
Presents an optimum mixture-design method for proportioning gap-graded concrete; based on mixture proportions of optimized cement contents to achieve various compressive strengths. It further develops a step-by-step procedure for using this method, together with an illustrative numerical example.
