1. Introduction. Calcium carbonate produced by biological activity (mainly by bacteria) is commonly named as biocement. This mineral is precipitated after the hydrolysis of urea by microorganisms. The precipitation of calcium carbonate occurs at high pH and is called microbially induced calcite precipitation, MICP.
