The recently held NRMCA Concrete Durability Course in Upland, CA, was attended by 23 industry personnel. The course was hosted by Holliday Rock at its headquarters. The course covered a broad range of concrete durability topics, including permeability, corrosion, sulfate resistance, alkali aggregate reactions, cracking and other factors. The coverage discussed basic mechanisms, test methods, methods to address durability when developing concrete mixtures and requirements in codes and specifications. This course offered the NRMCA Concrete Technologist Level 4 Certification. The course was taught by Michael Thomas, Kevin Folliard, and Colin Lobo. Holliday Rock is sincerely thanked for hosting the course.

The next course offering will be in the May/June 2016 time frame; when the location is selected it will be posted on the NRMCA Web site. For more information, contact Colin Lobo at
