When we started constructing out larger buildings we used a standard readymix company ( https://www.cranesville.com/) in our case and rented a concrete line pump. However, for this project we wanted to use a aerated/cellular/foamcrete ( goes by many names) so that we could experiment with carbon sequestration. 

When we started with AirCrete we used these plans https://www.etsy.com/listing/552397572/foam-mate-pdf and simple 7th generation soap.  This worked OK and we used it to create small structures like below, these were early prototypes.

However we switched to the Domegaia system for mixing AirCrete.
