- •
Precipitation of CaCO3 through CO2 influx is comparable with that of urea.
- •
Compressive strength increased up to 117% compared to control and 47% with urea treated specimens.
- •
Sorptivity significantly reduced in bacterial carbonated specimens than other treatments.
- •
Utilization of CO2 serves as an alternative to urea during CaCO3 precipitation.
