Alternative Materials - Bio-cement - RTF | Rethinking The Future

2020/12/21 · Microbially-Induced Carbonate Precipitation (MICP) used in the process of Bio-Cementation requires limestone to be heated at much lesser temperatures, using lesser energy, and has a lower carbon footprint. Thus, making Bio-Cement a rather eco-alternative to traditional cement with 38% better compressive strength than the latter.
