Maryland DOT State Highway Administration Approves Keystone® KeySystem™ II Retaining Wall System
MINNEAPOLIS (May 17, 2018) – The Maryland State Highway Administration (MSHA) recently issued approval of the Keystone® KeySystem II™ retaining wall system, using Keystone Compac® II or III and TenCate Miragrid® reinforcement for use on state highway projects for walls up to 50 feet high. KeySystem™ II is designed to the highest standards and unique requirements of the transportation sector. The system consists of Keystone Compac® II or III units and TenCate Miragrid® geogrids by TenCate...
Sturdy and Stylish
Anodized aluminum provides excellent durability and ease of installation for architectural exteriors, all while making fashionable, modern designs a reality Unlike any other metal available for the construction market, coil-anodized aluminum is uniquely suited to exterior architectural applications. Its unmatched durability, extreme light weight, high strength to weight ratio, and easy installation make it a highly functional material, while its three-dimensional look and ability to be c...

Contribution of Steel Casing to Single Shaft Foundation Structural Resistance
TRB's National Cooperative Highway Research Program (NCHRP) Research Report 872: Contribution of Steel Casing to Single Shaft Foundation Structural Resistance proposes revisions to bridge design specifications based on comprehensive analytical and testing programs for investigating the effects of steel casing. Bridges are often constructed with a single enlarged shaft foundation supporting a column. In many cases, the shaft foundation is constructed with a permanent steel casing. The combination...
AISI Publishes New Report on Thermal Analysis of CFS Wall Assemblies
WASHINGTON, D.C. – The American Iron and Steel Institute (AISI) has published the findings from research conducted to support the development of a calculation methodology for determining the U-factors and R-values for wall assemblies containing cold-formed steel. The research project was conducted by Morrison Hershfield Ltd (MH) and involved detailed thermal modeling simulations of 27 steel stud assemblies which varied by insulation thickness, insulation placement and steel stud depth. A summary...
CFSEI Publishes New Technical Note on the Attachment of Cold-Formed Steel Framing to Precast, Post-Tensioned and Hollow-Core Concrete
WASHINGTON, D.C.— The Cold-Formed Steel Engineers Institute (CFSEI) has published a new Technical Note, “Attachment of Cold-Formed Steel (CFS) Framing to Precast, Post-Tensioned and Hollow-Core Concrete,” designated as Tech Note F502-18. The document provides an overview of precast, prestressed, tilt-up, cast-in-place and post-tensioned concrete components for building construction and the various cold-formed steel anchorage options recommended for proper connections, including power-actuate...
High-strength Concrete Developed at MSU Could Save State Money, Time
BOZEMAN - In a lab at Montana State University, researchers use massive hydraulic pistons to crush samples of concrete in order to determine the material’s strength. To test what’s called ultra-high performance concrete, they’ve had to ratchet up the force. “One little square inch of this concrete will carry about 20,000 pounds,” said Michael Berry, a professor in the Department of Civil Engineering. That’s about five times stronger than regular concrete, he said. During the past two years...

Use of Cortec MCI-2005 Admixture Raises Seawall Service Life Prediction to 150+ Years!
A new reinforced concrete seawall off the Gulf Coast of Florida is predicted to last more than 150 years, thanks to a high density concrete mix enhanced with Migrating Corrosion Inhibitor™ admixture MCI®-2005. The owner of the structure had future generations in mind as he planned the construction of a new residence on the shore of Longboat Key. A seawall was needed to protect the shoreline from erosion, and the owner requested that the mix be designed with a minimum service life of 100...
Precast Wall Panel System Used for Airport FAA ALS Generator Building
BUFFALO, NY (January 2018) – Using precast concrete custom-made wall panels and hollow core plank, Oldcastle Precast Newnan, Ga., working in conjunction with CNS Communications, LLC, constructed the newly upgraded emergency generator runway light control building at Buffalo’s International airport. Owner of Buffalo International Airport, the Federal Aviation Administration contracted CNS Communications, LLC to provide an upgraded FAA Approach Lighting Systems (ALS) generator building for one...
