These guys have an interesting spin on the subject.
They give reasoned opinion that cellular concrete sucks!

It is always good to look at things from all angles.

I really like their insight on the role of thermal mass in construction.
Ideal insulation should be on the outside of the building envelope! Dur.


This has made me re-think how to build. I love it!

Looking into how the thermal mass thing works led me to:
CMPA - The Concrete Centre

Veddy Interesting!


I am adding a jUST IN
window because I am getting overwhelmed with new products
here is the latest >
I was just turned onto:
Envirolastech
http://www.envirolastech.com/products/
What they are doing with incinerated garbage is quite amazing.
At first glance it appears to be just another composite decking.
With further investigation that is not the case.
The "Structurally Load Bearing" property gets my attention!

I am not sure where to put them in the list yet. They seem to have a lot in common with Richard Bassaraba and Jonathan Hampton for being on the cutting edge.
Are they selling exotic cement? Check them out.

• Aerated, Foamed, Lightweight, Cellular Concrete
Cellular concrete is a lightweight building material that is both strong and has excellent thermal efficiency. A very cost effective, sustainable and green building material.

Not yet well known in North America it has been used throughout the world for almost 100 years.

Cellular concrete was developed in Sweden in 1914.
It was used to rebuild much of Europe after WWII.

THIS IS NOT pie in the sky or over the rainbow technology.
Here are several ways to achieve cellular concrete. I am sure there are more.

• Ceramic Cement - Over the rainbow cool mud technology

• Foamed Concrete - Used all over the world


• EPSCrete
- Used all over the world and my current favorite


• Autoclaved Aerated Concrete - I am not convinced

• Cellular Concrete - using a variety of lightweight aggregates that provide insulation value and strength

Below are the highlights of what I have found out about them.
Also listed are suppliers of tools and accessories for working with cellular concrete.

Ceramic Cement Guru

I recently became acquainted with Jonathan Hampton with the Ceramic Research Institute.

I believe what Jonathan has to offer to the world of construction has staggering implications.
Ceramic Cement is the NEXT EVOLUTION (in my humble opinion) towards truly green, sustainable construction.

Here is a page putting together the knowledge imparted to me so far by Jonathan:
http://www.greenearthstructures.com/ceramiccrete.html

Stay tuned for more as Jonathan's Star Wars Technology (for concrete) evolves.
I am very excited to see what happens next.


Mud Lite Guru
I have talked to many people about lightweight concrete.

Steve Brenna with Cellular Concrete knows more about the subject than anyone else I have communicated with.


I urge you to explore Steve's website and learn what this technology can do.

If you are thinking you might want to play with some Mud Lite Steve is the guy to talk to.

• EPSCrete - Lightweight concrete using mostly scrap styrofoam (My Current Favorite Mud Lite)
There are the companies I have found in North America using EPSCrete technology:
All of these products use up scrap polystyrene to make really cool (or warm) mud lite.

RASTRA Forms
http://www.rastra.com/
They say they are ICF (Insulated Concrete Forms) but they ain't your granddad's ICF form. No virgin polystyrene here!

CEMPO Forms, Inc.

http://www.cempo.com/
Building System Of The Future - Today

APEX BLOCK

http://www.apexblock.com/
I like the T&G feature on their block.

AMAZON FORMS

http://www.amazonforms.com/

These products all use recycled polystyrene to make really sweet mud lite block.

No poured in place (PIP) at all. Why?




Europe and Asia Are Way Ahead In The EPSCrete Development
Cast In Place (CIP) - Block - Panels - Roofs - Floors - Walls - ??
Production Plants - Mobile Units
Poured - Sprayed - Troweled
They are doing it all.
I urge you to take some time and check these sites out.

Coisoimper Advanced Technology - Italy
http://www.coisoimper.com/index.php?lang=en
From EPSCrete to Cellular Concrete (CLC)
products include panels, walls, blocks, screeds and geotechnical.

Tech Service Polska - Poland

http://www.techservice.info.pl/polytech/?lang=en
Roofs, floors, terraces, swimming pools, walls, insulating plasters and block

Siberian Constructing Technologies - Russia

http://www.sts54.ru/en/
They have a variety of products making mud lite from different sides of the technology including EPSCrete.

Simprolit - Russia

http://www.simprolit.ru/english/
Plates, block, panels & more.

It is interesting how much more this technology is overseas. I wonder why?



• Autoclaved Aerated Concrete (AAC)
This article is a good sketch of AAC technology:  http://www.pathnet.org/sp.asp?id=19776

For AAC the cellular concrete is poured into molds for either block or panels then cooked in an autoclave.

These products are then transported to the construction site and assembled.

Here are some suppliers of AAC block, panels and other
lightweight concrete products


Cresco Concrete Products
  http://www.crescoconcrete.com/  
866-491-6819, Houston, TX.
Cresco does a lot of different things with aerated concrete.
Including LiteBlok AAC block.

SafeCrete AAC
  http://www.safecrete.com/aac/aac.cfm
SafeCrete currently has a home going up in my area. I am keeping a close eye on the project and I will have more thoughts on what I think as it goes up.
1st Thought - don't hire masons to put this stuff in place. The factory recommends tile setters or GOOD carpenters.

Here is a good article on the structural behavior of AAC block:

• Cast In Place Cellular Concrete (CIPCC) - Use local materials to produce foamed concrete
Cast In Place Cellular Concrete (CIPCC)
is another method of building with cellular concrete using locally produced concrete - cutting down on transportation costs.

Portland cement and sand is mixed with foam to produce an aerated concrete mix.

The basic concrete mix can be ordered from your local batch plant and then mixed with the foam on site and then poured for walls, floors, roof, etc.

In my mind a great advantage of this method is transportation costs are very limited.

Another plus is you are getting a solid "cast in place" wall rather than a bunch of pieces glued together.
I am also thinking it should be quicker (less expensive) to put up.

NCT Construction - Malaysia

Introducing Waffle Box Building in 2013. Interesting. What could it be?


Why are we so far behind Malaysia & the Phillipines?
Here are some suppliers of products that can be used to make CIPCC happen in your backyard
Cresco Concrete Products   http://www.crescoconcrete.com/  
866-491-6819, Houston, TX.
Cresco does a lot of different things with aerated concrete.
Including LiteBlok AAC block.
Richway CreteFoamer http://www.richwayind.com/index.html?page=CreteFoamer manufactures a series of sizes of foam generators (everyone needs a foam generator).
All kinds of CIP cellular concrete supplies and information.
Cellular Concrete Solutions   http://www.cellular-concrete.com/products.htm
Cellular Concrete LLC has lots of information on poured in place cellular concrete. Check out their data sheets page. They sell the foaming agents, foam generators and offer technical support.
Goodson & Associates, Inc.  http://www.goodsonassociates.com/index.html  303.233.2244
Goodson caries many lightweight concrete products including (they say) the best foam generator around.
Vermillion LLC and Associates http://vermillionassociates.com/
foam concentrates, foam generators, reinforcement for concrete and other cellular concrete related tools. Vermillion also sell peristaltic (squeeze) pumps that are required to pump aerated concrete. Regular concrete pumps pop the bubbles and leave you with less aeration. Not good.
Precise Forms is a unique concrete form that might fit the job for CIP lightweight concrete: http://www.preciseforms.com/  

Here is another great formed in place aerated concrete idea:
http://www.casthome.com/home.php
When you are done with the modular forms they could be transported to the next hot spot designated as needing fast, low cost, strong housing and that has the basic materials needed to make this building system effective.


They are ahead of the curve in the islands.

I want to build some buildings like these!!!

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.

My Current Dream For The Perfect Green Building System
In My dream - CIPCC technology is used in a combination of EPSCrete, Green Concrete and a steel frame to produce buildings that would be almost entirely made from recycled materials!


I am continuing to research. I will keep this page updated.
