Earth Friendly Concrete

I was alerted to this product by this article on New Civil Engineer, which is entitled Keltbray Saves Carbon And Money With Earth Friendly Concrete On East London Job.

The article gave enough clues to find the Earth Friendly Concrete home page.

This is the introduction on the page.

We want to have a positive impact on the environment and supply our customers with an excellent product, that is why we created Earth Friendly Concrete ® by Wagners. It is a concrete that uses no ordinary Portland cement, instead using a geopolymer binder system made from the chemical activation of two industrial waste by-products – blast furnace slag (waste from iron production) and fly ash (waste from coal fired power generation). Our product has ZERO Portland cement and it has a much lower embodied energy compared to ordinary concrete, saving 250kg of CO2 for every cubic metre poured. Importantly, the engineering and construction properties of this environmentally friendly concrete is, in some areas, better than normal concrete. EFC has some significant performance advantages over normal Portland cement concrete, including improved durability, lower shrinkage, earlier strength gain, higher flexural tensile strength and increased fire resistance.

On this page, which is entitled About EFC, this said about the products Environmental Excellence.

EFC is a new class of concrete that contains NO ordinary Cement. Globally, the production of 1 tonne of Portland Cement produces 1 tonne of CO₂ emissions and is responsible for 5 to 8% of manmade greenhouse gas emissions. Instead of cement, EFC has a geopolymer binder that is made from the chemical activation of two recycled industrial wastes, flyash and slag. This recycled binder reduces the CO₂ emissions associated with Portland cement by 80 to 90%.

Every m3 of 40 MPa EFC saves 220kg CO₂ emissions.

Wagners, the company behind the development, are based in Queensland. Australia.

So it’s a case of Well Done The Aussies!

They have appointed Capital Concrete, to deliver Earth Friendly Concrete in the London area.

Conclusion

Does High Speed Two and other large projects that will need large amounts of concrete, know about this development?
