| Dispersive clays are a particular type of soil material in which the clay fraction erodes in the presence of water by a process of deflocculating and could cause significant problems in geotechnical and geo-environmental projects. Dispersive soils have been found to exist in various types of climates, especially arid climates, which the extent of dispersion mostly depends on mineralogy and clay chemistry. Bentonite, kaolin, and fibrous clay soils are among the most important and useful industrial materials. Therefore, clay dispersion potential was investigated by adding dispersive materials (Sodium hexamethaphosphate) and performing shear strength, crumb, double hydrometer, pinhole tests and chemical experiments. Stabilization practices using biological methods were done with Bacillus sphaericus and Bacillus pasteurii after soil divergence to assess the impact bacteria strains on soil improvement parameters. Bases on chemical properties, Sodium Adsorption Ratio and stabilization potential was in the order of kaolin>sepiolite>bentonite; the trend changed in accordance with clay CEC. The role of produced carbonate was prominent in improving mechanical and dispersivity properties. Soil chemical (exchanging Na ions) and mechanical (cohesion and friction angle) characteristics ameliorated by B. pasteurii further than B. sphaericus. In general, biological stabilization may replace conventional soil improvement methods as an eco-friendly and efficient way toward sustainable development. | ||
