Scope

INTRODUCTION In 1983@ at the First International Symposium on Fly Ash@ Silica Fume@ and Slag@ the author presented a comprehensive report on pozzolanic and cementitious by-products used in concrete (1). During the last five years a relatively large number of publications dealing with the subject have appeared. For example@ the proceedings of the Second Int'l Conference on Fly Ash@ Slag@ Silica Fume@ and Natural Pozzolans (Madrid@ 1986) contain 80 papers in a Special Publication of the ACT (SP-91)@ and the proceedings of the Eighth Int'l Congress on the Chemistry of Cements (Rio de Janeiro@ 1986) contains 4 special reports and 43 supplementary reports on the subject. In addition to numerous research papers that are routinely published in scientific and technical journals@ the author is aware of at least five books (2-5) and four committee reports (7-10) which attempt to cover the state of the art in a comprehensive manner. This review is not intended to be a digest of the 1983-87 publications on pozzolanic and cementitious by-products used in concrete. Instead@ it is the intention of the author to provide an update on the topics covered by the previous review (1) and highlight any new information which@ in the author's view@ represents a significant advancement to the state of the art. First@ a brief review of the more recent rates of production and utilization of pozzolanic and cementitious by-products in many countries of the world will be presented. This will be followed by new and useful information on their physical and chemical characteristics@ influence on concrete properties@ specifications and test methods@ and contribution of siliceous by-products in making concrete an environment-friendly material of construction.
