Earthbag Building 2.0 Contest — 1 Comment

  1. In just two hours or so, we’ve already received an outstanding entry from Tanzania. There’s no clay in the area, so their solution is to use 40% volcanic dust, 40% volcanic aggregate and 20% lime. (Lime is 1/4 the cost of cement in Tanzania.) This mix is currently being tested, but it sounds good to me. Thanks for sharing.
