President's Message

Welcome!  We are glad you are visiting our website.  We hope you find it useful for learning about California's construction and industrial materials industry.

CalCIMA members are local businesses that provide materials to meet California's construction and manufacturing needs. The website offers information on uses of aggregates, industrial minerals, and ready

mixed concrete.  It also has information on economic benefits, recycling, green building, and how we care for the land and natural resources.  And, it has news, up-coming events, and how to join CalCIMA.  The What's New page has the latest up-dates.

If you are interested in learning about how local materials help meet the challenges of global warming, please visit our related website,

Again, we hope you find our website informative.  Please let us know if we can be of assistance.
