The development of alternatives to soil stabilization through mechanical and chemical has paved the way for biostabilization methods. Since its development, researchers have used different bacteria species treatment. Soil treatment bioremediation techniques been understand effect on strength parameters contaminant remediation. Using a living organism binding grains make mass dense durable is ba...

This research focused on the evaluation of potential use a soil-isolated bacteria, identified as Staphylococcus equorum, for microbial-induced calcite precipitation (MICP) and copper removal. Isolated bacteria were characterized considering growth rate, urease activity, calcium carbonate precipitation, tolerance minimum inhibitory concentration (MIC) precipitation. Results compared with Sporosa...

To improve the mechanical properties of calcareous sand, it is proposed that microbial induced calcium carbonate precipitation (MICP) technology be used. A series solidification tests were conducted in natural seawater and freshwater environments. The standard stress path static triaxial apparatus was used to conduct shear on sand solids under varying reinforcement conditions. composite power-e...

This review aims to quantify the impact of calcium chloride in cementation solutions on Microbial Induced Calcite Precipitation (MICP). Specific soil strength properties, such as Unconfined Compressive Strength (UCS) test, permeability (k) and carbonate content soil, form basis quantifying test results. Relevant articles from various online databases Scopus, Science Direct, ProQuest Dissertatio...

In order to study the influence of microbial content on engineering properties expansive soil im-proved by microbially induced calcium carbonate (MICP) method, and clarify its law mechanism action, provide some theoretical reference for application MICP method treatment. Microbial reproduction their mineralization in soils have been studied. The problems such as moisture controlling low process...

Bio-cementation is a new sustainable approach that has gained popularity due to its low energy and carbon dioxide footprint compared with those of existing technologies for geotechnical geoenvironmental engineering applications. soil improvement technique involves binding the pore space particles calcium carbonate minerals by microbially induced precipitation (MICP) filling space. The purpose t...

Microbial-induced CaCO3 precipitation (MICP) is an innovative and rapidly developing technology for sand solidification. The idea this research project was built based on the concept of sustainable development environmental protection. specific material used solidification soluble calcium ions generated by reaction limestone waste, a kind calcium-rich industrial waste from quarry, acetic acid. ...

Microbial-induced calcium carbonate precipitation (MICP) technology mainly uses carbonates produced by the reaction of microbial activities to repair rocks and soils. Temperature influences metabolism kinetics chemical reactions. In this study, experiments on fractured sandstone under different temperatures are carried out. The effects tested with nuclear magnetic resonance (NMR), an X-ray auto...
