This article notes that high performance means more than high strength, and describes how many of the methods for obtaining high-strength concrete also improve such qualities as durability, workability, shear strength, and abrasion and impact resistance. Research to obtain high performance concrete (HPC) has focused on deflocculation using organic products, and extending the grain size range by addition of extremely fine elements to fill the microvoids. Approaches to obtaining high strengths are discussed. Characteristics of HPC are reviewed including microstructure, placing, mechnanical behavior, and durability. New approaches to structural design demanded by the new material are also discussed.
