Different amounts of these materials are combined with Portland Cement in varying percentages depending on the specific HPC requirements. Though there are many definitions for High Performance Concrete (HPC), the most widely-accepted one is that given by the American Concrete Institute, which states; “High Performance Concrete is concrete that meets special performance and uniformity requirements that cannot always be achieved routinely by using only conventional materials and normal mixing, placing and curing practices.” It is not possible to give a unique definition of HPC without determining the performance requirements of the intended use of the concrete. With the development of HPC, emphasis has in many cases – such as that designed for bridge and roadway construction - shifted from compressive strength to other properties of the materials, such as high density, low permeability and resistance to some forms of environmental attack. Though High Performance Concrete is often of high strength, not all high strength concrete is High Performance. The Federal Highway Administration has adopted criteria for this type of concrete: Freeze-Thaw Durability – the resistance of concrete to repeated cycles of freezing and thawing during cold weather Scaling Resistance – measures the amount of resistance to surface scaling in the presence of de-icing chemicals Abrasion Resistance – measures the amount of wear that will result from constant traffic loads Chloride Penetration – determination of depth to which concrete salts and de-icing agents will penetrate the concrete Elasticity – measure of the simple tension stress, which will be applied to concrete in use Shrinkage – determines the length change in hardened concrete due to causes other than externally applied forces or weather Creep – measures the tendency of concrete to slowly deform or move permanently under certain stresses Compressive Strength – amount of load that concrete will bear (measured in pounds per square inch) Ralph Clayton & Sons was the first company in New Jersey to supply a Department of Transportation project with High Performance Concrete for the Route 9 Bridge over the Raritan River. Other projects supplied by Ralph Clayton & Sons include: Route 35 Victory Bridge connecting Sayreville to Perth Amboy, NJ Routes 1 & 130 Intersection in North Brunswick, NJ Route 70 9/11 Memorial Bridge over the Manasquan River Brick Township to Brielle - the 2008 American Concrete Institute Grand Award winner Route 52 Causeway spanning from Somers Point to Ocean City, NJ Route 36 Highland Bridge Replacement at Sandy Hook, NJ Routes 1 & 9 St. Paul’s Avenue Bridge project in Jersey City, NJ GALLERY MANUALS & SPECIFICATIONS (PDFS) CHEMMASTERS Cure & Seal Catalog CHEMMASTERS Spray Film, Evaporation Retarder data sheet CHEMMASTERS Tech Tip – Decorative Concrete Bubble Formation in Sealer Sealer Delamination Maintaining Decorative Sealer Protecting Late Season Pours Using Sealers with Color Tints SDS - Concrete Safety Data CONCRETE BUILDER Concrete Calculator EDC MAGAZINE ARTICLES Concrete 2007: Building Today to Conserve the Future Concrete In Disguise Concrete’s Contribution Concrete Pavement Without the Runoff Students Thinking Sustainable Concrete Cement Manufacturing AMERICAN BUILDER VIDEO SERIES Segment on Stamped Concrete Pour CHEMMASTERS Polyseal EZ Video - Sealing & Stamped Concrete OUR CONCRETE PARTNERS Great Eastern Technologies L.M.
