Low-carbon concrete by CarbonCure Canada - lowering the carbon footprint of buildings

...CO2 is being introduced to the mix, so once the concrete hardens it is sequestered forever, and the other benefit is that adding carbon to concrete actually makes it stronger. That means between 5% and 7% less cement is needed to achieve the same compression strength. Using less of the most expensive ingredient offsets...
