The Monolithic Fabric Mixer is simplicity itself. The ingredients for a cubic foot or less of concrete are put into the center of this fabric. The fabric is then agitated from side to side by two people. The completed concrete can then be transported to its point of use.
This mixer is easy to use, very fast and absolutely simple.
The mix design we suggest for concrete Ecoshells for the fabric mixer is one container of cement, four containers of sand and water as needed. A good place to start is with 1 liter of cement, 4 liters of sand and 1 liter of water, adjust the water to the conditions. Adjust the sand if needed by adding some 3/8 minus pea rock.
