Microbially induced calcite precipitation (MICP) technique has gained attention recently as a novel method to enhance the engineering properties of soils, especially sandy soils. However, applicability this field scale is challenging and requires understanding factors affecting MICP process under variable subsurface conditions. This study presents laboratory investigation numerical predictive m...

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 ...

Microbially Induced Calcium Carbonate Precipitation (MICP) is a natural biocementation that takes place in corals, stromatolites and beach rocks. In recent years, researchers have explored the emulation of this process as sustainable alternative engineered cement. Although undoubtedly sustainable, its variant deviates substantially from process. paper, we investigate environmental economic perf...

Abstract Purpose Instability of slope surface is a critical concern in Geotechnical and Environmental Engineering. MICP (Microbial-Induced Carbonate Precipitation), an innovative bio-cementation technique, has attracted the attention for protection. In this work, was investigated to evaluate its durability under exposure acid rain advance understanding on long-term performance soil preserved by...

Most previous studies investigating the use of microbial-induced calcium carbonate precipitation (MICP) to reinforce foundations have indicated that final curing effect can be improved by changing nutrient environment parameters during MICP reaction. However, using such methods improve construction process increases cost and impact on surrounding environment. This study was conducted determine ...

The present work explores the adaptive behavior of well-known ureolytic bacterial strain namely Sporosarcina pasteurii for microbial-induced calcite precipitation (MICP) under saline environment. MICP activity was observed up to 10% NaCl supplementation and confirmed by several characterization techniques viz. scanning electron microscopy (SEM), X-ray diffraction (XRD), thermogravimetric analys...

In recent years, oil spills and leakages have often occurred during exploration, transportation, handling, usage, processing, causing serious global environmental problems. Microbially-induced carbonate precipitation (MICP) is an emerging green, environmentally friendly, sustainable technology that has proven to be a promising alternative for soil stabilisation. This paper provides comparison b...

After exposure to high temperatures, the mechanical properties and durability of concrete structures are significantly reduced, effective measures must be taken for reinforcement repair. High-temperature damage manifests as looseness, spalling, cracks, which suitable microbial-induced carbonate precipitation. When repairing high-temperature with precipitation (MICP), calcium source is an import...

It is difficult to collect and characterise well-preserved samples of weakly-cemented granular rocks as conventional sampling techniques often result in destruction the cementation. An alternative approach prepare synthetic geomaterials match required specifications. This paper introduces microbially induced carbonate precipitation (MICP) a method reliably deliver artificially cemented specimen...
