Indiana Mineral Aggregates Association - IMAA

The Indiana Mineral Aggregates Association represents over 90% of aggregate production in Indiana. It is our goal to provide the best educational programs, networking opportunities, and collaborative working atmosphere for our membership. The purpose of the Indiana Mineral Aggregates Association is to solve common problems of the Indiana aggregate producing industry, principally in the areas of specifications for aggregates, mine safety and reclamation, air and water pollution, legislation, research for improvements in aggregates used, increased public awareness of the importance of aggregate products in their daily lives, and broadening the use and application of aggregates in Indiana. In 1934, Indiana Mineral Aggregates Association was formed to solve common problems of the Indiana aggregate producing industry. The major changes in the industry have been a result of changes in equipment. Equipment transformed the amount of production and created other needs for producers. As a result, the association takes an active role in multiple areas including specifications for aggregates, mine safety and reclamation, air and water pollution, legislation, research for improvements in aggregates used, increased public awareness of the importance of aggregate products in their daily lives, and broadening the use and application of aggregates in Indiana. The Indiana Mineral Aggregates Association has a long history of working to serve its members and plans for a bright future in the aggregate industry.
