Japanese researchers are unveiling a fast-setting, CO2-absorbing material that could be used to rapidly rebuild earthquake-hit areas. It needs an epoxy-resin type substance to provide tensile strength (rather than rebar reinforcement as with conventional concrete), but once it has set, its strength rivals conventional concrete. I do have quite a few questions:
- Any claims on longevity?
- Does it require pure CO2 to set, or could the tailpipe emissions from a power plant do the trick? This is a huge question in terms of its overall sustainability.
- Um, cost?
But for special applications, the increase in setting time and supposed strength enhancements over concrete could be an enormous selling point.
Our company Nu-Rock Corporation SARL has perfect this process but using all the ash from coal fired power stations and we can use all 30 million tonnes from power station in Japan. We can turn all the ash from fly ash to bottom ash into Silica Cement.
We can make a product including cement and sand, aggregate, blocks panels pipes, which is half the weight and the same strength and acid and salt attach resistant.
The cost is 50% cheaper than Portland cement products.

We are building two 500,000 tonne plants at power stations in Australia
