About California’s Aggregate Industry

CalCIMA is a statewide trade association for aggregate, ready mixed concrete, and industrial mineral operations. The members of CalCIMA provide California with construction materials such as concrete, asphalt, and road base. These materials build roads, bridges, homes, hospitals, walkways, and water structures. CalCIMA members also provide essential ingredients for beer, wine, vitamins, nutrients, and soil enhancements, as well as for paint, roofing shingles, glass, pipes, brick,  plastic, and artistic elements.  CalCIMA members operate about 500 plants in California.
