Principles Underlying Production of High-Performance Concrete

Abstract

Abstract Durability rather than high strength appears to be the principal characteristic for high-performance concrete mixtures being developed for use in hostile environments such as seafloor tunnels, offshore and coastal marine structures, and confinement for solid and liquid wastes containing hazardous materials. Strength, dimensional stability, impermeability, and high workability are usually the principal characteristics required of high-performance concrete. In this paper an overview of the composition of concrete and its effect on the properties desired for high performance is given. This overview can be used as a basis for selection of component materials and mix proportioning. A new step-by-step procedure for mix proportioning is described. The calculated mix proportions from this procedure appear to be consistent with the state-of-the-art laboratory and field practice. Also, a brief review is given of concrete production and construction practices essential for making a high-performance end product.
