About IMAA

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.

Aggregate operations create attractive job opportunities and a strong tax base for local communities. Aggregates are essential construction materials for residential and commercial development, as well as for improvements to infrastructure projects such as roads, bridges, dams, hospitals, schools, and water/sewer systems. All of this supports the quality of life we enjoy.

In the last few years, Indiana aggregate companies have produced nearly 75 million tons of crushed stone, sand & gravel, slag, and similar products. They employ approximately 2,300 workers and pay almost $100 million in wages and over $4 million in state income taxes.

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.
