Soil stabilisation is the process of changing one or more of the soil's qualities in order to meet certain requirements. During this procedure, both ureolytic and non-ureolytic bacteria were utilised to manufacture urease enzymes, which were then utilised to hydrolyze urea into ammonium and carbonic acid. Calcium ions, along with the assistance of bacterial cells, are necessary for the precipitation of calcium carbonate cement. This precipitation coats the soil particle to produce a soil cement matrix, which ultimately boosts the desirable mechanical properties of the soil matrix, including its strength and stiffness. Microorganisms can be found in natural soil, but some of them can be dangerous to humans. On the other hand, there are many types of microorganisms that are quite beneficial. Because of this, I had a crystal clear concept to use microorganisms for the purpose of stabilising clay soil, and Bacillus subtilis and Bacillus megaterium were utilised for this project. With the assistance of bio-augmentation, a process known as MICP (Microbial Induced Calcite Precipitation) is utilised in order to combine the microorganisms found in the soil sample. In this instance, I made use of the liquid form of bacterial cells together with cementation reagent, which is comprised of urea, calcium chloride (cacl2), nutritional broth, and distilled water. This reagent is made with 0.25M, 0.5M, 0.75M, and 1M, and the bacteria were added with a soil sample consisting of 2%, 4%, 6%, and 8% of the cured product after 7, 14, 21, and 28 days. As a result of this, I need to determine the appropriate ratios in order to achieve the desired level of durability in the soil sample. The UCS and CBR tests were carried out for varying amounts, and the results were compared with those obtained using Bacillus subtilis and Bacillus megaterium. Clay soil is used as the soil sample because the strength determination may be determined with relative ease. When specific nutrients and clay soil are combined, the microorganisms Bacillus subtilis and Bacillus megaterium are utilised as a stabilising agent. This allows for the soil to maintain its structure. The soil sample ought to be compacted at the obtained dry density and moisture content, and the test that was carried out shows that the values of CBR and UCC attained the peak strength of adding 6 percent of microbes; however, once the strength is increased beyond this limit, it begins to decrease, with bacillus subtilis showing the maximum peak strength in comparison to bacillus megaterium. Based on the findings, I came to the conclusion that incorporating bacteria into soil is an effective method of soil stabilisation. The MICP is a very cost-efficient method, and it is possible to make a very large quantity of it at a very reasonable price. In comparison to other alternative methods of stabilisation, the cost of the cementation reagent is rather low. It is not only long-lasting but also kind to the environment, which bodes well for the future.
