I just came across this stuff, and a search showned no previous mention on here.

We spend a lot of time on here worrying about the energy consequences of using too much concrete. Certainly as I detail an extension I can see how it is hard to avoid if trying not to be _too_ unconventional.

So, has anyone any experience of Zeobond e-crete? It's stuff like concrete with very similar performance but with only 20% of the carbon footprint in production and only 10% more expensive. Which sounds promising. Been available in australia for a couple of years.

Best overview of why it's good:

manufacturers lite:

Anyone see any reason not to use this stuff (one may be that it's not available in the UK yet)?

Despite it being Sunday here, and 3am in Oz I got a response already:

No, Zeobond's concrete will not be available in the UK at any time soon. The reasons are that the supply chain in the UK is tightly controlled by cement interests, and moreover, most of the European construction materials applications are regulated by prescriptive standards instead of the performance- based standards we increasingly have in Australia and to which the US is moving. Zeobond has activities in the UAE and China where we have some influence on how new performance standards should be formulated. As you may know I also chair a RILEM committee to address the evolution in the standards regime and culture. See: http://www.rilem.net/tcDetails.php?tc=AAM Ultimately, the market will decide whether they want green products, reduce greenhouse gases and push for regulatory and cultural change, without which it will not succeed.
Best wishes.
