Mechanical and environmental assessment of Biobricks material

Zanchetta, Enio
2018

Microbial-induced calcite precipitation is a biochemical process of biomineralization. The process form mineral crystals composed of calcium carbonate and if precipitated into a sand matrix can lead to the formation of sandstone. The sandstone created in such way has the advantage of using a low amount of energy and even sequestrating CO2. This study aimed at comparing the environmental benefit of this material compared to classical building materials. The mechanical characteristics of the material were also assessed to have a first insight of the possible future applications as building material. X-ray computed tomography was conducted to assess the microstructural parameters of this material called “Biobricks”. Mechanical tests were performed and possible links between microstructure and strength evaluated. A life cycled assessment was conducted in a second part to quantify the environmental benefits of the material.
