A review of the literature on the influence of aggregate grading on the properties of concrete revealed a diversity of opinion concerning the optimum gradings of fine aggregates. In most of the investigations dealing with the amount of material passing the No. 100 sieve that will produce satisfactory concrete, it was indicated that less than 15% of this size material is desirable, and it was concluded that 10% is optimum for mass concrete. In general, the consensus was that fines cause an increase in the water requirement and influence air content. One of the studies reported indicated that high air content did not decrease the strength excessively for mass concrete and seemed to be beneficial. Therefore, it appears that a mass concrete mixture low in fines and having a high air content may prove satisfactory. It was generally concluded that the fine-aggregate grading influences in varying degrees the workability, durability, strength, water requirement, air content, bleeding, and density of concrete.

Phase I of this investigation consisted of a review of literature dealing with influence of fine-aggregate grading on properties of concrete. This report presents results of Phase II, a laboratory investigation of the effects of variations in fine-aggregate grading on certain properties of mass concrete mixtures.

Bringing together in one volume the latest research and information, this book provides a detailed guide to the selection and use of aggregates in concrete. After an introduction defining the purpose and role of aggregates in concrete, the authors present an overview of aggregate sources and production techniques, followed by a detailed study of their physical, mechanical and chemical properties. This knowledge is then applied to the use of aggregates in both plastic and hardened concretes, and in the overall mix design. Special aggregates and their applications are discussed in detail, as are the current main specifications, standards and tests.

This highly successful textbook has been comprehensively revised for two main reasons: to bring the book up-to-date and make it compatible with BS8110 1985; and to take into account the increasing use made of microcomputers in civil engineering. An important chapter on microcomputer applications has been added.
