• Portland Cement Association (PCA)
  Since its founding in 1916, the Portland Cement Association 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.
  The makeup of today's PCA reflects these functions and the industry's diversity with a network of divisions and affiliate groups. This structure takes advantage of collaboration with allied organizations.
