Scale model of a concrete block (used as barriers etc) manufactured from concrete made with aggregate (C8S 2) manufactured from cement by-pass dust, (C8S 1) using Accelerated Carbonation Technology. Sourced from Carbon8.

Scientists at Carbon8 Systems have found a way to treat industrial residues, like the fine powder on display, with captured carbon dioxide.

Their ‘carbonation in a box’ technology turns the residues into aggregates – the larger granules – that are then used to make concrete. This technology can be added to existing industrial sites, so that companies can reduce their carbon dioxide emissions and avoid sending waste to landfills.

This is a model of a concrete “legio” interlocking block made using this process. It is usually used for barrier construction. Concrete is manufactured from aggregate (c8 2), manufactured using Accelerated Carbonation Technology from cement by-pass dust (c8S 1) and CO2 .
