An experimental approach to microbial carbonate precipitation in improving the engineering properties of sandy soils

Abstract Purpose Stabilization of weak soil can be achieved through different methods, some which include jet column, cement stabilization and fly ash stabilization. Unfortunately, the use aforementioned methods improvement affects environment negatively thereby leading to environmental degradation. With aforesaid impediment in mind, need for devising becomes pertinent. Methods Bacillus sp . — a non-pathogenic organism found abundantly was investigated this study as potential agent improvement. The usability sp. with direct shear tests permeability under optimum conditions study. Result Time-dependent on effect ureolytic bacteria sp.- induced calcium carbonate precipitation shows reduction increase strength On exhaustion available nutrients soil, however, is not impacted. Conclusion Microbially by effective such it may serve substitute conventional techniques. ability precipitate leads soil.
