Abstract EN
Sporosarcina pasteurii, a common soil bacterium has been tested for microbial treatment of cement mortar.
The present study also seeks to investigate the effects of growth medium, bacterial concentration and different buffers concerning the preparation of bacterial suspensions on the compressive strength of cement mortar.
Two growth media, six different suspensions and two bacterial concentrations were used in the study.
The influence of growth medium on calcification efficiency of S.
pasteurii was insignificant.
Significant improvement in the compressive as well as the tensile strength of cement mortar was observed.
Microbial mineral precipitation visualized by Scanning Electron Microscopy (SEM) shows fibrous material that increased the strength of cement mortar.
Formation of thin strands of fillers observed through SEM micrographs improves the pore structure, impermeability and thus the compressive as well as the tensile strengths of the cement mortar.
The type of substrate and its molarity have a significant influence on the strength of cement mortar
