Biomason biocement

Biomason biocement is made with calcium carbonate (CaCO3) produced by microorganisms and provides an alternative to Portland cement. Through a process of microbiologically induced calcium carbonate precipitation (MICP), microorganisms react with chemical components to produce minerals suitable as binding agents. As well as having potential as a building material, it is used for reinforcing soils, such as is important for transport infrastructure and sea defences. As an example, Biolith is a precast product consisting of approximately 85% natural aggregate and 15% biocement material. Image Biomason.
