According to the references I found online, Earthcrete varies a lot in formula - paper fibers, ceramics, industrial by-products, clay, other minerals. It uses almost no portland cement. Earthcrete is what they are calling a product made by Sonoma Cast Stone.
And yes, you should not put clay in concrete. Earthcrete is not concrete, nor is it cement stabilized soil.

Both earthcrete and concrete should be mixed with just enough water tomake them workable, and I don't think a tow mixer would work for stirring them. You want more of a slow paddle action.What's earthcrete? Combination of cement and soil? I thought there was some discussion on here recently that said you couldn't successfully combine clay and cement?
