Hands Can Make Poor Concrete
In many parts of the
world a shovel and a ditch are the only concrete mixing
solution. This crude mixing system, plus skimping on
cement and adding too much water, leads to the issues
that we all have witnessed in the 2010 Haitian
It is understandable
that this type of mixing has been adopted in poor
communities where labor is cheap and codes are ignored
or don’t exist. It is nearly impossible to produce
consistent concrete using this method.
It is unfortunate
and even tragic to rebuild a home using the same poor
quality construction methods as before, and then loose
it again during the next natural disaster.
The first step in
producing a consistent concrete mix is to insert a
mechanical version of the “mixing ditch” into the
The second is to accurately
measure the materials that enter the mixer.
is good, but a measured batch-box is better.
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.
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.

Concrete M.D. (mixing ditch) will produce up to
1/2-meter batches of quality concrete, in even the most
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
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.
The mixer can
produce 3-meters of ready-mix concrete each hour and
will employ several workers in loading and then
delivering the finished concrete.

The Concrete M.D. can be the
cure for many of the ills of poor concrete mixing.
The unit ships in a package that includes the Honda

sized for a standard foundation/slab/wall recipe and
complete operational instructions.
