In the Spring of 1952, acting on the invitation of a producer active in the field, expanded shale producers from the United States and Canada met in St.Louis to discuss a plan to form an organization of producers. The meeting resulted in the formation of the Expanded Shale, Clay and Slate Institute as a non-profit, technical organization supported by the producers of expanded shale, clay or slate by the rotary kiln process. The major objectives of the organization are:
- To improve and extend the uses of expanded shale aggregate through research and development;
- To disseminate the authentic data developed to the architectural and engineering professions and to the construction industry;
- To cooperate and collaborate with other technical organizations interested and active in the field of concrete;
- To maintain standards for uniformly high quality of product among the membership.
