Calcite is one of the most common and wide spread mineral on Earth constituting 4 wt% of the Earth’s crust.
It is naturally found in extensive sedimentary rock masses, as lime stone marble and calcareous sandstone in marine, fresh water and terrestrial environments.
Calcium carbonate is one of the most well known mineral that bacteria deposit by the phenomenon called biocementation or microbiologically induced calcite precipitation (MICP).
Such deposits have recently emerged as promising binders for protecting and consolidating various building materials.
Microbially enhanced calcite precipitation on concrete or mortar has become an important area of research regarding construction materials.
This study describes a method of strength and water absorption improvement of cement–sand mortar by the microbiologically induced calcium carbonate precipitation.
A moderately alkalophilic aerobic Sporosarcina pasteurii was incorporated at different cell concentrations with the mixing water.
The study showed that a 33% increase in 28 days compressive strength of cement mortar was achieved with the addition of about one optical density (1 OD) of bacterial cells with mixing water.
The strength and water absorption improvement are due to the growth of calcite crystals within the pores of the cement–sand matrix as indicated from the microstructure obtained from scanning electron microscopy (SEM) examination
