1. A Cure For The
World’s Poorest
Construction
Quality Concrete
from Simple Tools

2. Solving the Concrete Crisis
For generations, Charitable Organizations have helped local populations
recover from the devastation of floods, earthquakes, tsunamis, and hurricanes.
At first they triage and treat the immediate medical needs of the victims and
establish an improved level of comfort for the suffering. These efforts save
lives and improve the chances of a community to recover from the disaster.
The second phase is often less newsworthy, but equally important. That is the
phase where shelter, roads, water systems and other parts of the infrastructure
are rebuilt. Organizations lend a hand directing the rebuilding efforts using
local labor and local tools and methods. Unfortunately, in most cases, this has
just rebuilt the
substandard types of
facilities that have
been the victims of
the most recent
disaster.
By rebuilding dwellings, for example,
using inconsistent construction
methods, we are often merely setting
up a repeating cycle of devastation. This is most evident in concrete
production. Most buildings are built with foundations or walls made of
concrete and other cement products. Concrete is mixed by hand, on the
ground, with little or no control of the quality of mix. The result is a building
that is built on a foundation (and with walls) that will barely hold their own
weight. By making simple changes to the quality of concrete construction,
buildings can become real shelter instead of future hazards.
Weak concrete structures, susceptible to destruction, are weak for two
reasons: Poor quality concrete and lack of reinforcing bar in the construction.
The weak concrete affects all structures. The lack of rebar is most critical in
larger and multiple story buildings.
In the past, getting quality concrete to typical under-developed sites has been
either prohibitively expensive or physically limited by power costs. We can fix
this…

3. Many 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 Haiti this past
year.
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
process.
The second is to accurately measure the
materials that enter the mixer.
A bucket is good, but a measured batch-
box is better.
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 Haiti. 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.

4. 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-meter 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 Haitian
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.
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.
With the enormous volumes of concrete that
must be produced in Haiti, we can put many
people to work using Concrete M.D’s for building
foundations, columns, walls, roofs and various building blocks.
By decentralizing ready-mix production we can complete several smaller
projects simultaneously and train many Haitians to make better 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 powered hydraulic power unit, two batch-
buckets that are sized for a standard
foundation/slab/wall recipe and complete
operational instructions.
Final testing and introduction of this new mixer is scheduled for September 31st
2010.

5. Producing Better Concrete is our Goal
Cart-Away Concrete Systems is the leader in providing efficient tools to raise
the standards of concrete production, without sacrificing the simplicity needed
for remote locations. We have been producing these mixing solutions for over
17-years. The new Concrete M.D. meets the goal of rebuilding devastated
communities using a combination of simple tools and our best engineering.
We propose that you join with us in providing better, more consistent concrete
for Haiti. This can be accomplished in two steps:
1. Place Concrete M.D. mixers in the hands of Haitian construction workers to
assist them in building back better homes and businesses.
2. Then leave the mixers behind in the hands of Haitian entrepreneurs to continue
building strong concrete structures with the better tools.
We believe that getting these mixers into the hands of Haitian workers will
speed the rebuilding efforts. We can fulfill the immediate need to rebuild
today and then we can assist in continuing the process of building with better
concrete in the future.
First, mixers need to be purchased as a
program expense and then placed
strategically around the country at
various construction sites. Each mixer
will include simple batching/mixing
instructional materials that illustrate the
value of producing consistently strong
concrete, using proper mixing
procedures.
One Concrete MD can supply
concrete for about 5 or 6 homes
per day and employ 6 to 8 Haitians
to handle the mixing and
dispensing duties.
Finally, after the international aid
organizations leave, the mixers
can be left in the hands of Haitian
entrepreneurs who can become
the local ready-mix supplier and
employer to their neighbors for
years to come.

6. We can Build Better Concrete
Cart-Away has many years of experience assisting with the start-up, training
and implementation of small concrete enterprises. This experience could be
adapted to the Haitian concrete training process to support the idea of
rebuilding with more trustworthy concrete mixes.
Concrete is the most consumed product on earth, besides water. It is not hard
to produce a simple concrete structure that will withstand earthquakes and
other natural events. With just a few adjustments to their construction
processes and with a better tool for mixing, developing nations can build
homes, hospitals, churches and schools where they can confidently find safety
from disaster.
We stand ready to be a part of the solution, and help the Haitian people to
build back better with concrete. We hope that we can work with you to meet
this objective.

7. The CUBE alternative
The Cart-Away C.U.B.E. is a traditional drum mixer that
includes an overhead loading conveyor. The CUBE has been
working successfully for the past 4-years in many remote
locations; from FEMA dam projects in the mountains, to resort
construction in the Bahamas.
There is currently a CUBE working in Haiti to construct an orphanage and
church by Builders International.
The CUBE conveyor will accept material loading by a skid-steer, a super-sack
or by the hand-carry bucket. The mixing drum has a capacity of 1 cubic meter
(1.5 Yards) and discharges by tilting the drum down to load tractor buckets or
wheelbarrows.
A CUBE, a tractor and 5-man team could support about 8 to 9 homes per day.
The CUBE ships as a single unit with dimensions: 48”W x 78”H x 132”L
Shipping weight: 3500#
