A Novel Approach for the Consolidation of Sand by MICP Single Treatment

Saving natural resources has become increasingly important. In construction, research been done on alternative methods to replace conventional building materials. One of those novel is MICP (microbial induced calcium carbonate precipitation). this process, crystals are precipitated with the help ureolytic bacteria. A cementation solution consisting urea and salt used. This precipitation can be used for solidification. field research, there exist multiple publications several kinds tests, but no verifiable compressive strength test. However, most researchers concerned soil improvement or self-healing methods, fill cracks in concrete. Similarly, column tests mainly conducted investigate strength. study presents, a new method assay that uses hardened sand samples 3 cm edge length. allows an accurate verification thus effect biocementation treatment. addition, applies single treatment type formulation components. The results show sufficient consolidation various sands. Compressive up 1.8 N/mm 2 was achieved process uniaxial
