A technique to produce bio-cementation in sandy soil using the microbially induced calcium carbonate precipitation (MICP) process and calcium ions generated from eggshell is presented in this research. This research also focused on the application of S. pasteurii bacteria and L. fusiformis bacteria along with eggshell and calcium chloride cementing chemicals on the strength properties of sand. The experimental variables maintained in this research are bacteria type (S. pasteurii and L. fusiformis), cementing chemical type (eggshell and calcium chloride) and molarity of the cementing chemical (0.25, 0.50, 0.75 and 1.0). The engineering behaviour of bacteria treated sand was estimated by executing the unconfined compression test and permeability test in the laboratory. From the experimental findings, it is identified that the unconfined compressive strength of sand is enhanced and the value is in the range of 650 kPa. In addition to that, the permeability of sand is minimized in the order of two from 6.3 × E |
