GREEN CONSTRUCTION

Biological stabilisation of soil simply refers to the stabilisation of soil is achieved through biological means like planting or afforestation or more complex biological processes. The term “soil stabilisation” refers to the process of increasing the stability and bearing capacity of the soil using proportion, controlled compaction, and/or the addition of suitable admixtures or stabilisers. Mechanical improvement and chemical treatment are the two other main techniques used to create engineered soil.

Importance of Biological Soil Stabilization

Increasing demand for usable land for developments necessitates exploring alternate techniques for ground and soil treatment. In Particular, methods should have minimal impact on the environment and at the same time enable the recycling of factory byproducts. The disposal of fly ash from thermal power industries has been a difficult problem that urgently needs a solution. Finding a reliable and environmentally friendly alternative binder, such as cement, is thus required.

ENZYME AND CIVIL ENGINEERING

There are some emerging and innovative applications where enzymes and biotechnology are being explored in civil engineering. One such area is the use of microbial-induced calcite precipitation (MICP) for soil stabilisation. Certain bacteria can produce enzymes that facilitate the precipitation of calcium carbonate, which can strengthen loose or unstable soils. This technique is being researched as a potential method to improve the engineering properties of soil in some geotechnical applications

Biocementation En:zymes can be used to promote the precipitation of minerals and bind soil particles, enhancing the stability and strength of soil. This process, known as biocementation, can be utilised in soil stabilisation and erosion control.

Biodegradation: Enzymes can assist in the biodegradation of organic compounds and pollutants, such as oil spills or contaminants in soil and groundwater. Bioremediation techniques that involve enzymes can help clean up polluted sites.

Concrete admixtures: Enzymes can act as admixtures in concrete formulations, improving the workability, setting time, and strength of the concrete. They can also be used to enhance the performance of self-healing concrete by promoting the repair of micro-cracks.

Waste management: Enzymes can play a role in waste management by assisting in the decomposition of organic waste materials. They can be used in composting processes to accelerate the breakdown of organic matter into nutrient-rich compost.

Soil remediation: Enzymes can assist in soil remediation by breaking down contaminants or pollutants, making them more accessible for removal or degradation.
