Article
This paper examines the possible use of a bio-cementation process to reduce excessive bulging that occurs during the loading of granular columns in soft clays. A 12-phase percolation biochemical treatment technique was used to bio-cement part of the columns targeting the columns upper section, where bulging usually occurs. Upon application of unit...

Thesis
Bio-grouting by means of microbial induced calcite precipitation (MICP) has received significant research attention over the last decade as it has the potential to outweigh existing ground improvement techniques and mitigate environmental concerns with currently used materials. Although bio-grouting process and its implication on the improvement of...
Article
Biocementation processes rely on microbial-induced calcite precipitation (MICP), which is a naturally occurring biochemical process. Biocement materials are a form of environmental cementitious agents used to improve the mechanical properties of granular soils by physically binding soil particles together. Efficient improvement of the macromechanic...

Conference Paper
This paper discusses the results of small-scale model tests that were undertaken to investigate the behaviour of un-cemented and bio-cemented coarse sand columns installed within a soft clay bed. The tests also focused on studying the effect of biocementation to reduce excessive radial expansion and settlement that may occur during installation or...
Article
Current permanent ground anchor standards require the use of double protection systems encapsulating the steel strands, to ensure a serviceable design life. In recent years, where steel reinforcement use was restricted due to aggressive ground conditions, carbon fibre reinforced polymer (CFRP) reinforcement was successfully used as a durable constr...
Article
This paper focuses on using urea hydrolysis as a bio-grouting process to increase the strength of crushed aggregates commonly used in stone columns. Various reagent phases (2, 4, 6, and 12 phases) consisted of alternately percolating solutions containing bacterial suspension and cementation solution through the soil column. In addition, a multi-soi...

This paper investigates the effectiveness of microbially induced calcite precipitation (MICP) method in improving the strength and stiffness of coarse sands using treatments based on a four-phase percolation technique. An increase of biochemical treatment cycles was associated with increased deposition of calcium carbonate (CaCO3) and consequentl...
Article
Microbial-induced calcite precipitation (MICP) has received increased attention in recent years as a potential technique for green soil improvements. MICP mimics natural biochemical processes, but utilises cultured urease-producing bacteria that more efficiently catalyse the hydrolysis of urea in the presence of calcium ions to induce precipitation...

Article
The effect of grain size distribution on the unconfined compressive strength (UCS) of bio-cemented granular columns is examined. Fine and coarse aggregates were mixed in various percentages to obtain five different grain size distributions. A four-phase percolation strategy was adopted where a bacterial suspension and a cementation solution (urea a...

The nanoparticle is used into cement pastes to improve its engineering properties. In this paper, silicon carbide (SiC) and titanium carbide (TiC) nanoparticles with a particle size (20 nm) were added at different percentages 1%, 2%, 3%, 4%, 5% and 6%) to cement pastes. The cement pastes were tested for mechanical and physical properties at differe...

Bio-grouting by means of microbial induced calcite (calcium carbonate) precipitation (MICP) to improve mechanical properties of granular soils has gained much attention in recent years. The bio-grouting process offers an alternative and environmentally friendly approach to conventional soil improvement techniques, such as cement. Bio-grouting by ur...

Use of a sustainable and environmentally friendly material such as bio-cement to stabilize sand particles has been proven to be an effective soil improvement technique. This technology has been widely explored in various geotechnical applications. Bio-cementation process involves hydrolysis of urea by bacteria containing the enzyme urease in the pr...

This paper investigates the feasibility of using a soil-lift bio-grouting treatment strategy to improve the mechanical properties of coarse sand with the view of applying it to stone columns/sand piles and rammed earth columns type of applications. A two-phase percolation approach was adopted in this study that included percolating a bacterial susp...
Article
This paper describes the soil stabilization process of gypseous soil with various percentages of lime and cement, separately. The soil used was brought from Abu Ghraib city, west of Baghdad, and the gypsum content of the soil is found to be 35%. To improve this soil, numerous soil specimens were prepared by adding different percentage of lime or ce...
