The Spring 2019 National Concrete Consortium held in Lakewood, CO, from April 1 - 4 attracted a historically high 210 professionals from the industry, 32 state highway departments and NRMCA staff that included Don Clem, Colin Lobo and Karthik Obla. The event featured discussions on the implementation of Performance Engineered Mixtures (PEM) tests such as resistivity, SAM and formation factor. Karthik Obla presented on the “Role of Minimum Cement Contents in Concrete Specifications and Mixture Proportioning.” There were also presentations on mass concrete, mobile-mixer and fiber-reinforced concrete for use in overlays and bridges.

The event concluded with a tour of the U.S. Bureau of Reclamation laboratories which conduct unique tests such as cathodic protection, adiabatic calorimetry, shear, creep and strength tests on a 5 million lb. machine. Its services are available for use by outside groups. The tour featured breaking a 2 feet diameter by 4 feet high concrete cylinder (click here to view a video).
