Production

Do you have any experience using the residue coming from coal fired electric plants?
We have an abundance of that here in our area which are being thrown away.
And one of the big power plants has allowed us to take it for FREE.

Would that be a suitable material to use in making the interlocking bricks?

If so, what would be a good ratio to start with?

I was interesting in knowing what particular material is used to produce brick with different colors

Hi Geoffrey

any comments on the embodied energy of CEBs vs fired clay mix bricks or other traditional alternatives would be much appreciated!

Cheers,

Dan

Hi Geoffrey,

Just after some more general information regarding CEBs, especially the ratio of cement needed as an admixture and the potential of other less CO2 intensive materials like RHA to be partial or full replacements as stabilising/binding agents?

Kind regards,
Dan

Dear Geoffrey,

do you know whether there is a lab/institute in Chiang Mai who can conduct compression strength tests for blocks?

thanks & best regards,
Nhien

Hello dear Geoffrey
Before I began to make stabilized ICEBs, I wanted to check if the soil-sand mix was good for compression and had the right proportions of each component. So I pressed a few samples that appeared to be fine.

My question is, do they need to be somehow cured or treated in any special way to become useful for interior walls or other not heavy load applications?
Cheers,

Greetings from sunny Kenya!
have acquired two derelict block making machines (which were used for CEB a while back) These machines have been unused for over a decade and are rather stiff. am looking for assistance as to how to service these machines and how to get the 'ram' section to raise as it would when 'dispensing' the block
Any advice would be greatly appreciated!

Greetings Geoffrey,
Will you be holding any seminars or other training opportunities for production of and/or construction with ICEBs in 2015?
Thank you!
 

Thank you, Geoffrey for answering my many questions. I appreciate you sharing your knowledge and experience.
I've read that the ideal soil mix for solid CEBs is:
15% gravel (2-20 mm)
50% sand (0.06-2 mm)
15% silt
20% clay
What are your thoughts on this ideal mix?
Our soil here is very sand with measurable amounts of silt and clay  in various places (up to 20% clay and silt combined).

Greetings from West Africa,
Do you have any training opportunities scheduled for 2014? especially in Rhino block production and construction?
Thank you.
