STRENGTHENING OF COASTAL SANDS BY USING GELLAN GUM AND OPTIMIZED MICROBIALLY INDUCED CALCITE PRECIPITATION

Excessive effluent ammonia limits the potential ground improvement applications of the Microbially Induced Calcite Precipitation (MICP) process due to its harmful environmental consequences. Alternatively, innocuous biopolymers are being researched for strengthening soils, but their hydrophilic natu...
