Meet CalCIMA

The California Construction and Industrial Materials Association (CalCIMA) is the statewide voice of the construction and industrial materials industry.  With over 500 local plants and facilities throughout the state, producing aggregate, concrete, cement, asphalt, industrial minerals, and precast construction products, our members produce the materials that build our state’s infrastructure, including public roads, rail, and water projects; homes, schools and hospitals; assist in growing crops and feeding livestock; and play a key role in manufacturing consumer products as well, including roofing, paint, low-energy light bulbs, and battery technology for electric cars and windmills. The continued availability of our members' materials are vital to California’s economy, as well as ensuring California meets its renewable energy, affordable housing, and infrastructure goals.
