Cementation Mechanism of Microbe Cement
摘要
Abstract
Cementation mechanism of microbe cement was investigated by X-ray diffraction, scanning electron microscopy (SEM) and transmission electron microscopy (TEM), respectively. SEM results showed that the morphology of microbially induced formation calcite was sphere and spherical aggregate, but that of chemical formation calcite was oblique hexagonal body. In addition, the microstructure of sandstone cemented by the above methods was similar. TEM results indicated that the crystal particles of microbially induced formation calcite was smaller than that of chemical formation calcite and the loose particles could be cemented by microbially induced formation calcite, however, it could not be cemented by chemical formation calcite.关键词
