ABOUT PCA: Since its founding in 1916, the Portland Cement Association has had the same mission: ‘Improve and expand the uses of portland cement and concrete.’
Where cement and concrete are concerned, so is the Portland Cement Association: in manufacturing, in raising the quality of construction, in improving our product and its uses, in contributing to a better environment. In practice, this mandate means well-rounded programs of market development, education, research, technical services, and government affairs on behalf of PCA members-cement companies in the United States and Canada.
ABOUT CTL Group: For more than 95 years, CTLGroup has provided clients in the construction, transportation, minerals, and related industries with a unique blend of engineering, testing and research services. Its home offices are in a 120,000 sq-ft complex in Skokie, Illinois. The firm, which began as the research and development arm of the Portland Cement Association, started serving outside clients as an independent PCA subsidiary in 1987. Since then, CTLGroup has developed into a world-class resource for materials technology and civil and structural engineering.
