American Concrete Institute
The American Concrete Institute announces the availability of two new publications of interest to decorative concrete contractors:
234R-06: Guide for the Use of Silica Fume in Concrete — This report describes the physical and chemical properties of silica fume; how silica fume interacts with portland cement; the effects of silica fume on the properties of fresh and hardened concrete; recent typical applications of silica-fume concrete; how silica-fume concrete is proportioned, specified, and handled in the field; and areas where additional research is needed.
25.13R-06: Concrete Overlays for Pavement Rehabilitation — This report provides information on the use of concrete overlays for rehabilitation of both concrete and asphalt pavements. Selection, design, and construction of both bonded and unbonded overlays are discussed. The overlay categories reviewed include: bonded concrete overlays, unbonded concrete overlays, whitetopping overlays, and concrete overlays bonded to asphalt (ultra-thin and thin whitetopping). Information is also provided on selecting overlay alternatives. Significant portions of this document are based on a synthesis report prepared for the Federal Highway Administration by Applied Pavement Technology.
