Figure 5. Determination of water retention capacity: Three columns were prepared using 2 ml syringes placed in test tubes to check the water retention ability of the bio-cement. Positive control column was established by mixing commercially available CaCO3 and marine soft clay in 1:1 ratio; Test column was established by mixing bio-cement and marine soft clay in 1:1 ratio. Negative Control column consisted of only marine soft clay. To all the three tubes 1.5 ml of water was added slowly and water leakage was recorded intermittently for a period of 2 days. The representative pictures were taken after 0 hours (A), 3 hours (B), 18 hours (C) and 72 hours(D) respectively : Strengthening Water Retention Capacity of Marine Soft Clay Using Bio-cement : Science and Education Publishing
