Dispersive soils which occur in many parts of the world are easily erodible and segregate in water pose serious problems of stability of earth and earth retaining structures. The mechanism of dispersivity of soils is reasonably well understood. However there is simple method to identify the dispersivity of the soils and even more difficult to quantify the dispersivity. Visual classification, At...

–A detailed investigation has done Redmud an Alluminium industrial waste product has done to study its feasibility for use in road constructions. In this study Redmud was stabilized with 2, 4, 6, 8,10and 12 percentages of lime and unconfined compressive strength, Split tensile strength and California bearing ratio tests were conducted at 1, 3, 7 and 28 days curing periods respectively. From the...

Two soils spiked with lead at different rates were stabilised/solidified using Portland cement and fly ash at different soil:binder ratios and tested for their setting time, unconfined compressive strength (UCS), leachability and durability. Results show that soil texture, percentage of binders and lead concentration play an important part in the treatment, significantly influencing the perform...

Abstract The undrained shear strength (Su) and cohesion (Cu) of cohesive soils are frequently determined using an unconfined compression test. However, the test results heavily dependent on specimen size. This causes uncertainty in geotechnical analyses, constitutive models, designs by overestimating or underestimating soils. Therefore, study aims to assess effect height-to-diameter ratio compr...

the total coal and lignite consumption of the thermic power plants in turkey is approximately 55 million tons and nearly 15 million tons of fly ash is produced. the remarkable increase in the production of fly ash and its disposal in an environmentally friendly manner is increasingly becoming a matter of global concern. studies for the utilization of fly ash in turkey are necessary to reduce en...
