Royal White has developed a calcium sulfoaluminate (CSA) cement suited to agencies specifying very high early strength concrete for highway or runway pavement construction or repairs, plus customers seeking a CSA base in precast production or grout, shotcrete and underlayment applications. RWC CSA Cement attains compressive strengths of 4,000, 6,000 and 10,000 psi at three hours, 24 hours and 28 days, respectively.
Royal White has secured California Department of Transportation and U.S. Air Force approvals for the product, following early private construction market deliveries in the Southwest and Mid-Atlantic. The producer is initially supplying RWC CSA Cement from its Houston and Philadelphia terminals, and will extend availability from sister facilities—Vancouver, B.C.; Long Beach and Stockton, Calif.; Lake Park, Fla.; Savannah, Ga.; Kansas City, Mo.; and, Chesapeake, Va.—as market development progresses. RWC CSA Cement joins signature white portland cement and masonry cement offerings, and will be shipped in bulk, super sacks or 50-lb. bags. — www.royalwhitecement.com
