Project Description
Concrete MD: A Field Mixer and More

The MD is perfect for many projects
Easy to Operate
Quality Concrete even with Shovels and Buckets
By using simple recipes and consistent measuring, the Cart-Away Concrete M.D. (mixing ditch) will produce up to 1/2-yard batches of quality concrete, in even the most remote villages. And the mixer will work faster and produce better concrete than any other manual process.
The Concrete M.D. fits nicely into the common concrete production methods of the local workers. Their shovels will load the raw materials into the batch-boxes and their buckets will work for transporting the wet concrete to the forms.
Using an engine-powered hydraulic system; the counter-rotating auger can replicate and improve upon the action of several shovels blending the raw materials at the same time. The difference is that there is a consistency of mixture that shovels cannot produce. Concrete needs uniform blending in order to produce a strong mixture.
Dry Material Mixing
The Block MD cures the problem of blending dry powdery materials by using an aggressive mixing auger design. The paddle design mixes through very dry materials and blends the recipe well.
Wet Material Mixing
Measured batches of raw materials and cement are joined by water in the mixing chamber before going into the hydraulic block press.
Dispensing Tube
The 6” dispensing tube at the bottom of the mixing chamber allows workers to rapidly pour wet concrete directly into buckets or wheelbarrows for transport to the forms. A simple door controls the flow between bucket loads.
Perfect for Remote Locations
Quality block production can be accomplished with the MD and local unskilled labor. The highly portable MD allows blocks to be produced in remote locations. Well mixed block recipes can be used for building much faster than before. They reach full strength and become water resistant after a 28-day cure period.
Cart-Away Concrete Systems, Inc is the world leader in creating small concrete batching solutions. We have adapted one of our proven mixing processes to build a mechanical version of the mixing ditch to solve the concrete issues in the poorest countries of the world. This unit produces consistent mixes from a unique, yet simple batching process.

The Concrete MD - A Sustainable Cure for Poor Concrete
To sustain the earth's limited raw materials we must produce good concrete. The poor mix cement on the ground using shovels. The Concrete MD is a sustainable mixing technology that helps the poorest builders to produce strong concrete. -
Shovels are a portable cement mixer failure
Mixing concrete on the ground is a failed process of cement mixing. Developing nations still use this practice and it must be stopped.
Concrete mixing requires a good concrete mixer. -
Shovels mixing concrete on the ground - the Disaster Recipe!
In the poorest nations of the world the concrete is produced using shovels on the ground. CementTrust is drawing attention to the disastrous results of this practice. -
CementTrust Haiti Rubble Crusher
CementTrust has linked Cart-Away and ACTECH to create a new rubble crusher for the Haiti reconstruction efforts. Prototyping is underway at the ACTECH facility in Vancouver Washington. -

Killing themselves with shovels - concrete mixing
We are trying to help rebuild Haiti. But if we don't help them to make better concrete, they will not have a strong foundation. -
Haiti Concrete MD portable cement mixer
This is our newest concrete mixer built for developing countries. History has shown, as seen recently in Haiti, that developing countries are mixing concrete on the ground with shovels. This method of mixing concrete is not consistent and produces weak concrete. This new machine has batch boxes and a recipe right on the mixing chamber to insure consistent strong concrete. It also discharges into either a bucket, wheelbarrow, or right into the forms.
