Microbially induced carbonate precipitation (MICP) mainly uses urease-producing bacteria to hydrolyze urea to produce carbonate ions and contact the introduced calcium ions. The gelatinous calcium carbonate is deposited on the surface of loose particles and binding unconsolidated materials together. It has a great potential to complete many applications as a technologies of construction. In this work, the rate and ratio of depositing CaCO 3 in the process of MICP at various micro-environments was evaluated. Furthermore, more suitable conditions to promote the process of depositing was presented
