LAVA-Volcanic Architecture

Volcanic Cinder availability is spotty around the world.  Right now several Volcanic concrete companies I know of are in Arizona, New Mexico, Oregon and Colorado using different aggregates and techniques.  The only LAVA machines are in Arizona, developed to support Scoria volcanic aggregates.  Plans are underway to expand to other states.  Ultimately LAVA concretes will be most practical anywhere Scoria, Pumice, Tuff etc. are locally available.
