2019 Natural Pozzolan Association (NPA) Symposium

The first annual NPA Symposium was held at Rancho de Los Caballeros in Wickenburg, Arizona. The event was a great success, with a terrific mix of Natural Pozzolan industry leaders; from researchers to geologists, to cement and fly ash companies throughout the world. We want to thank all who attended, and look forward to our next Symposium in 2020 in Colorado. For more information about the Natural Pozzolan Association, check out the NPA website:
