I've been researching the idea of building domes and/or vaults with lightweight concrete on the Big Island. This concept is not new...the Romans built the pantheon about 1900 years ago and it is still standing. It is a huge dome whose roof was party concrete and partly pumicecrete (a mixture of cement and pumice).
Since cinder is somewhat heavier and stronger than pumice I would think it would make a good building material for domes/vaults especially if adding steel reinforcement. It should also have some attractive insulative as well as thermal mass properties.
Anyone out there know of anyone who has used cinder in this manner? Where? How?
