A Study on the Effects of Waste Rubber Tire Dimensions on Fine-Grained Soil Behavior
Mashhad city is located on alluvial deposits where the expanded area of this city, especially the central and eastern areas surrounding Imam Reza holy shrine, are built on weak and fine-grained deposits. Therefore, the soil improvement would be inevitable due to construction of high-rise buildings such as hotels and commercial complexes in these areas, as well as restructuring old buildin...
متن کاملEffect of class F fly ash on fine sand compaction through soil stabilization
This paper presents the results of an experimental investigation carried out to evaluate the effect of fly ash (FA) on fine sand compaction and its suitability as a material for embankments. The literature review demonstrates the lack of research on stabilization of sandy material using FA. The study is concerned with the role of FA content in stabilized soil physical characteristics. The main ...
متن کاملSelectivity of Particles through Rill Erosion in Different Soil Textures
Sediment selectivity during transport may provide basic information for evaluating on-site and off-site impacts of the soil erosion. Limited information is, however, available on the selectivity of sediments in rill erosion, particularly in the rainfed furrows. Toward this, the sediment selectivity was investigated in three soil textures (loam, loamy sand sand clay loam) under 10% slope using 9...
متن کاملBiodegradation of sorbed chemicals in soil.
Rates of biodegradation of sorbed chemicals are usually lower in soil than in aqueous systems, in part because sorption reduces the availability of the chemical to microorganisms. Biodegradation, sorption, and diffusion occur simultaneously and are tightly coupled. In soil, the rate of biodegradation is a function of a chemical's diffusion coefficient, sorption partition coefficient, the distan...
متن کاملAssessment of bioavailability of soil-sorbed atrazine.
Bioavailability of pesticides sorbed to soils is an important determinant of their environmental fate and impact. Mineralization of sorbed atrazine was studied in soil and clay slurries, and a desorption-biodegradation-mineralization (DBM) model was developed to quantitatively evaluate the bioavailability of sorbed atrazine. Three atrazine-degrading bacteria that utilized atrazine as a sole N s...
