| • Green
Cement - Concrete Using No
Portland Cement? One
of
the
big complaints about using concrete to build anything green is
the fact that it takes a lot of energy to produce the portland cement
used in making portland cement.
I would argue concrete is far superior to using the last remaining trees on the planet to put up flimsy structures for bugs to eat and storms to blow away. However the enormous amounts of energy consumed in the making of portland cement - is still a valid point. What if there was an alternative way
to make cement using vast
amounts of waste materials and no
portland cement? Richard
has worked in the cement industry for many years and has a
patent on turning flyash into
a superior substitute for standard portland cement. Richard is in the
process of putting up a website and starting to market his green
cement. I will link to it as soon as it is up and running. The
big
hurdle I see here will be overcoming the current
legitimate hysteria about all the flyash blowing and flowing into the
environment from dumps all over the world where power companies have
been dumping the stuff.
Richard has taken concrete technology to a
whole new level.My call is once you encase the flyash in a concrete structure the danger is nil. Flyash is already used to produce concrete and has proven a valuable and cost saving ingredient in standard portland based mixes. |
| • Reinforcing Fiber
For Concrete - Essential ingredient (to me) in
almost any
concrete mix There
are
many different types of fibers sold to
reinforce
concrete.
Here are three I have had experience with.
Natural Basalt Fiber. http://www.basaltfm.com/eng/fiber/application.html Completely natural and stronger than steel. HELIX stainless steel fibers are the most interesting addition to concrete I have seen. Putting HELIX fiber in concrete almost eliminates rebar. No joke. - See: http://www.helixfiber.com/index.html Nycom 800-456-9266 http://www.nycon.com/ Kuraray RECS15fiber-8 fibers are supposed to be unique in that they bind with the concrete. |
| • Concrete Additives - Modern concrete is likely to
contain additives designed to enhance performance and workability
I
just
found
Enhance ICD Inc.
(403) 998-5505 (Cell Canada), (702) 715-4027 (Cell USA) http://www.enhance-solutions.com Enhance ICD makes several interesting products to enhance concrete and mortar performance. I am most interested in their cement hydration catalyst (PMT). Sounds like it is performs miracles in concrete. Here is some technical stuff on PMT: http://ferrocement.net/flist/index.php?topic=169.65;wap2 |
| • Ceramic
Concrete Board - Magnesium Oxide Board or MgO Board
This
product
replaces drywall, wall sheathing,
roof sheathing,
floor
decking,
etc. MgO board is also used for poured in place concrete forms. The MgO
board is left in place after the temporary supports are stripped. The
MgO board can then
be finished. Water proof, mold proof, fire proof, insect proof. WOW!
Magnesiacore.com MgO Board http://magnesiacore.com/ 905-794-1333 - sells MgO board. I was quoted about sixty five cents a square foot for 12mm x 4' x 8' sheets delivered to Oklahoma City. Jonathon Hampton with the Ceramic Research Institute comes highly recommended 479-899-7053. Check out this Wikipedia article on MgO wallboard: http://www.en.wikipedia.org/wiki/Magnesium_oxide_wallboard MBP Magnum Building Products http://www.magnumbp.com/ 813-314-2202 DRAGONBOARD http://www.dragonboard.com/ 866-447-3232 CeraTech 800-708-7963 http://www.pavemend.com/ ceramic cement products NCI Panel Systems http://www.ncisteel.com 845-565-1000 makes modular panels using MgO board. They ship the panels - you assemble them and pour them full of cellular concrete. Wa La you have a building. Veddy interesting. |

• Cementitious
Foam
Insulation - Can be
used in a variety of different ways
Along
with
changing the way we build new structures we need to address
upgrading the existing buildings to bring them up to new energy
standards. Here is a product that can be used
in new construction and retrofitting older buildings.
Cellular
concrete
is not just used in
new construction pouring walls,
floors and roofs.
Blow concrete in a wall for insulation? Certainly wouldn't burn. Bugs won't like it. Could not get much greener. |

| I
recently
was
contacted
by: EnStyro 563-542-7255 http://www.enstyro.com/ I see great potential in EnStyro's business plan. They are making equipment to harvest the vast amount of scrap polystyrene (EPS) currently being thrown away and putting it to good use. |
Using
EnStyro's
foam shredding
equipment: http://www.enstyro.com/mobile-recycling-equipment/
produces
aggregate
from
local
EPS
waste
suitable
for
making
EPSCrete
to
form
and pour walls on site. All from locally acquired materials that
would otherwise wind up in the dump. Another great plus is that this
would save
on shipping any kind of block around the country. Use the Green Cement
to make the
StyroCrete and you are using almost 100% local recycled material to
pour bomb proof walls, floors, you name it. I may be in love. |

I traveled to Watts Oklahoma to visit Eugene Sargent Creations http://www.eugenesargent.com/ Eugene and Jesse Thomas with Ziacrete http://blog.onevillage.tv/?p=380 479-445-8593 ziacrete@mac.com. Eugene and Jesse are experimenting with cast in place and formed block cellular concrete on Eugene's very impressive new art studio built with CIPCC. Eugene is also into using ferrocement. Check out the FC bench on his website. |
I am continuing to research. I will keep this page updated.
