    May 28, 2020 Concrete is the second most consumed product by humans, after water. However, the production of conventional concrete causes more than 5 of anthropogenic CO 2 emissions and therefore there is a need for emission-reduced construction materials. One method to produce a solid, concrete-like construction material is microbial-induced calcium carbonate precipitation MICP.
