This video is by David Easton, the well known owner of Rammed Earth Works in California and author of The Rammed Earth House, the best selling book on the subject.
Here’s Wiki’s description: “Soil cement is a construction material, a mix of pulverized natural soil with small amount of Portland cement and water, usually processed in a [mixer…]. Hard, semi-rigid, durable material is formed by hydration of the cement particles.”
Soil cement is another great way to make affordable floors, patios and extremely strong fill material for earthbags. [Note for new readers: most earthbags are not stabilized, but there are certain applications where soil stabilization is a good idea.] Google “soil cement” to learn more about this subject.
Even though the video is about making pavers, I was more interested in David Easton’s soil cement recipe. This is why I love the Internet. Thank you David.
