Vermeer, Dwell Earth and Cart-Away join efforts to upgrade CEB’s
Improving cement-based construction methods for the world’s poorest people is the mission of CementTrust. Over the past year you have read of our efforts to improve cement mixing technology and to get the shovels off the ground for making concrete.
Now we are involved in mixing earth and cement to create better CEB’s. We are pleased to have been asked to participate with Dwell Earth and international equipment manufacturer Vermeer to help create an appropriate mixer for stabilized earth blocks.
Vermeer family members, the Vermeer Foundation and Dwell Earth have committed to developing, building and distributing the technology that will move the CEB system to the next level for developing nations. CementTrust and Cart-Away are anxious to assist them in this worthy effort.
The beauty of compressed earth is that the main ingredient is earth, and soil is very abundant. They use a small amount of Portland cement in the mix to stabilize and seal the blocks against the effects of weather, then they use hydraulic pressure to form a good block.
What is unique to this project is the technology that improves the strength and consistency of the blocks themselves. This is where Dwell Earth and Vermeer have been focusing their attention at Vermeer’s Pella, Iowa facilities.
A major issue in the success of the product is getting a consistent blending of cement and soil before water is added into the process. This is where Cart-Away and CementTrust have joined the effort to create a Compressed Earth Block Mixer.
The mixer development team at Cart-Away Concrete Systems was asked to design an auger for the Concrete MD that would aggressively mix the dry soil and cement powder so that it would be ready for use in the earth block press.
The goal is to provide a multi-use mixing machine that produces consistent concrete for the foundation of the building and then quickly changes to produce the earth block mixture for the Dwell Earth/Vermeer block press. Once blocks are produced the Concrete MD is converted back again for producing mortars, plasters or more concrete for bond beams.
Developing an all-inclusive system will save on the equipment needed to build strong structures in very remote areas of the world. It will also lessen the financial impact from investing in so many different pieces of equipment.
Dwell Earth and CementTrust are on the very same page in their desire to see these systems put into the hands of local communities to employ workers and to raise the economic security of poor nations. If the local builders have access to better tools they will benefit financially and live in safer structures.
