Microbe cement as a biogrouting could consolidate loose particles to improve mechanical properties. Microbe cement has drawn much attention because of the ever increasing awareness of environmental protection. This paper confirms the feasibility of binding loose sand particles using microbe cement and details the cementation mechanism of microbe cement. In addition, the microstructure and properties of representative bio-sandstones have been analyzed by X-ray computed tomography (XRCT), Scanning electron microscopy (SEM) and Mercury Intrusion Porosimetry (MIP). The experimental results indicate that the compressive strength of bio-sandstone could be up to 6.1MPa and the bottom region microstructure in bio-sandstone is denser and less fragile than the top region due to more calcite precipitated in the former one.
