Abstract: Recycling of waste material is one of the effective solutions of its disposal problem. Fly ash produced by coal-based thermal power plants and phosphogypsum (PG) produced by fertilizer plants producing phosphoric acid as ...

Abstract: This paper presents the shear strength characteristics of a low lime class F fly ash modified with lime alone or in combination with gypsum. Unconfined compression tests were conducted for both unsoaked and soaked specimens ...

Abstract: Physicochemical and microstructural developments of a low-lime fly ash modified with 6 and 10% lime and 1% gypsum were studied through X-ray diffraction, differential thermal analysis, scanning electron micrograph, and ...

Abstract: This paper presents the results of a laboratory investigation on tensile strength, bearing ratio, and slake durability characteristics of a class F fly ash stabilized with lime alone or in combination with gypsum. The ...

Abstract: Stabilization of fly ash is one of the promising methods to transform the waste material into a safe construction material. The longevity of lime-stabilized fly ash is related to the amount of lime that remains in the ...

Abstract: The physical processes such as advection, dispersion, and diffusion and interaction between the solution and the soil solids such as sorption, biodegradation, and retention processes have been considered in the governing ...

Abstract: Disposal of fly ash on land amounts to sacrificing precious land space. Recycling of fly ash is one of the methods of solving the disposal problem. Stabilization of a low lime fly ash with lime and gypsum was studied through ...

Abstract: Finite-difference method (FDM) has been adapted herein to solve a one-dimensional (1D) contaminant transport model to predict contaminant migration through soil in waste landfill underlying an aquifer. Providing an effective ...

Abstract: This paper presents the study on compaction characteristics of pond ash. Three different types of pond ash have been used in this study. The effects of different compaction controlling parameters, viz. compaction energy, ...
