Abstract:
The article discusses testing of a system designed to achieve overall carbon negativity. The system comprises a concrete slab supporting a wall constructed using concrete masonry units (CMUs). The concrete slab was made of alkali-activated cement containing algae-derived carbon-storing, biogenic limestone. The CMUs contain biomineralizing microalgae and a proprietary hydrogel binder as cement replacement.
