Technically it is 'mortar'. 'Concrete' implies the use of gravel. It would be interesting to know if the mixture was heavily modified with chemical additives to give and maintain that particular flowability and to extend/reduce the setting times. Very cool project.

You raise an interesting point: Cement is the expensive part and you lower cost by using bigger aggregates. A mostly cement house is, environmentally, pretty horrific.
