AltusGroup, Inc. is a national partnership of 17 precast concrete companies and seven industry suppliers founded in July 2003 to develop, manufacture and market precast concrete innovations throughout North America.〔(Six form first-ever precast concrete partnership ) retrieved 2010-06-11〕 Innovations include the CarbonCast line of technology that uses C-GRID carbon fiber grid for shear reinforcing developed by Chomarat North America. == History == AltusGroup emerged from a development initiative between Oldcastle Precast and Chomarat North America, formerly TechFab, LLC. Chomarat North America first conceived commercial grid structures using fiberglass roving and epoxy in 1997. It was initially named, “PetroGrid,” and introduced by Amoco Fabrics & Fibers Co. in 1998 to create geo-grids for the road paving market. In 1998-99, Chomarat North America and Oldcastle Precast entered a joint development agreement to explore the use of carbon fiber structural grids for use in concrete. The original precast product champion and technology visionary was Harold Messenger. From 1998-2001, development efforts focused on product, process, testing, and engineering design validation surrounding grid use in concrete. Dr. Thomas Harmon,〔(Thomas Harmon Professor & Director of Undergraduate Studies The Clifford W. Murphy Professor of Civil Engineering )〕 a professor of engineering at Washington University, St. Louis, provided primary research support for the initiative, also co-funded by both companies. Early research and development works serve as the engineering design basis used today to design and manufacture CarbonCast. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「AltusGroup」の詳細全文を読む スポンサード リンク
