Abstract:
Discusses special concretes used in transportation structures to attain properties that cannot be achieved with conventional concretes. The properties of principal concern are a low or very low permeability needed to prevent penetration of the concrete by chlorides, sulfates, or other deleterious solutions, and a high-early strength to permit early opening to traffic. The special concretes discussed are those containing slag; those with pozzolanic additions (silica fume, fly ash); latex-modified concrete; concretes made with Pyrament-blended cement; and portland cement with a low water-cement ratio for fast-track construction. Field applications and supporting laboratory investigations conducted by the Virginia Transportation Research Council of the Virginia Department of Transportation are reported that document the characteristics and superior performance levels of these special concretes.
