This guide presents a generally applicable method for selecting mixture proportions for high-strength concrete and optimizing these mixture propor- tions on the basis of trial batches. The method is limited to high-stmngth concrete produced using conventional materials and production techniques. Recommendations and tables are based on current practice and infor- mation provided by contractors, concrete suppliers, and engineers who have been involved in projects dealing with high-strength concrete. Keywords: aggregates; capping; chemical admixtures; fine aggregates; fIy ash; high-strength concretes; mixture proportioning; quality control; specimen size; strength requirements; superplasticizers.
