An Efficient Method of Estimating and Analysing Soil Moisture Using IOT
Abstract: The current state of water content on the earth is decreasing at a rapid rate. Due to this reason, the lands which used to be fertile, moist, and healthy for agriculture purposes and various other forest regions are drying out due to lack of moisture content. Excess water in various regions can be diverted to the lands with low moisture levels and converting them into fertile plain lands. The recent …

Structural, Optical, Surface, and Gas-Sensing Properties of rGO/Sn1–xZnxO₂ Nanocomposites
Abstract: rGO/Sn₁–ₓZnₓO₂ nanocomposites with x = 0.00–0.75 were synthesized by sol–gel auto-combustion followed by wet impregnation with reduced graphene oxide. The adopted synthesis route enabled homogeneous Zn incorporation into the SnO₂ matrix and uniform distribution of rGO, leading to improved structural integrity and interfacial contact between the two components. XRD confirmed a dominant tetragonal cassiterite SnO₂ structure, while FTIR, FESEM, EDS, UV–visible, and BET analyses verified oxide–rGO coupling, Zn-dependent structural modification, …

Numerical Simulation of Mitigation of Soil Swelling Problem under Communication Tower Using Helical Piles
Abstract: AbstractExpansive soils exhibit significant volume changes with variations in soil moisture content. Expansive soils are often considered as problematic soils. It undergoes large volume changes upon wetting and drying and causes huge damages to the structures resting on it. Numerical modeling was carried out by using PLAXIS 3D-2013 software, in which modeling the soil by using hardening soil model was done. Tower rested on expansive soils are subjected to uplift …

Ground Improvement Techniques for Stabilization of Black Cotton Soil by Using Fly Ash
Abstract: In India 22% of the geographical area is covered by expansive ‘Black Cotton Soil’. These soils are characterized by their highly swelling and shrinkage properties. In dry conditions these soils have high strength which is almost completely lost when they come in contact with water. These soils are having high degree of expansion which creates a lot of problems during the execution of work and after completion of it. Hence, …

A Review on Stabilization of Expansive Soil Using Different Methods
Abstract: Expansive soils are difficult soils for construction purposes because of their cyclic swell/shrink behavior. These soils undergo significant expansion when subjected to an increase in water content or shrink under evaporation condition (when water out). Bulging soils can be improved in several ways. Either by adding materials such as cement, lime, sand and adding river mixture soil. or these soils treated with chemical additives. When added to expansive soils in …

Settlement of Soil while Digging
Abstract: While digging of soft soil, collapse of soil takes place. When load of man is more than bearing strengthof soft soil, the soil will settle down. Hence bearing strength of mud soil is found at a particular depthand this is compared with load coming due to man. If weight of man is more as compared to bearingstrength of wet soil, the settlement will occur. The process of excavation in soft …

ENHANCING THE STRENGTH OF BLACK COTTON SOIL WITH ENZYME AND INDUSTRIAL WASTE
Abstract: Expansive soils are troublesome and prone to ground movements, which can cause substantial damage to underlying buildings as well as a loss in bearing capacity. Moisture fluctuation activates the expansive character of soils, causing it to swell and shrink. This has long been known in geotechnical engineering. To treat expansive soils, a variety of stabilizing additives such as lime, cement, and fly ash have been employed. In recent years the …
