RISCompaction Characteristics and Bearing Ratio of Pond Ash Stabilized with Lime and Phosphogypsum
Publisher: American Society of Civil Engineers
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 ...
Strength Characteristics of Class F Fly Ash Modified with Lime and Gypsum
Publisher: American Society of Civil Engineers
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 ...
Microstructural Development in Fly Ash Modified with Lime and Gypsum
Publisher: American Society of Civil Engineers
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 ...
Tensile Strength Bearing Ratio and Slake Durability of Class F Fly Ash Stabilized with Lime and Gypsum
Publisher: American Society of Civil Engineers
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 ...
Leaching of Lime from Fly Ash Stabilized with Lime and Gypsum
Publisher: American Society of Civil Engineers
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 ...
Finite Difference Method for Computation of 1D Pollutant Migration through Saturated Homogeneous Soil Media
Publisher: American Society of Civil Engineers
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 ...
Three-Dimensional Analysis of Contaminant Migration through Saturated Homogeneous Soil Media Using FDM
Publisher: American Society of Civil Engineers
Abstract: Finite-difference method (FDM) is applied herein to solve the three-dimensional (3D) contaminant transport model to predict pollutant migration through clay liner or clay deposit in waste landfill. The seven pollutant ...
Hydraulic Conductivity and Leachate Characteristics of Stabilized Fly Ash
Publisher: American Society of Civil Engineers
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 ...
Interpreting Results from the NARCCAP and NA-CORDEX Ensembles in the Context of Uncertainty in Regional Climate Change Projections
Publisher: American Meteorological Society
Abstract: AbstractTwo ensembles of dynamically downscaled climate simulations for North America?the North American Regional Climate Change Assessment Program (NARCCAP) and the Coordinated Regional Climate Downscaling Experiment ...
Analysis of 1D Contaminant Migration through Saturated Soil Media Underlying Aquifer Using FDM
Publisher: American Society of Civil Engineers
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 ...
