This study assesses the geotechnical performance of a compacted bentonite-sand mixture with a bentonite content ranging from 15 to 30 % by weight to be used as a material component in a waste sealing system. Geotechnical laboratory tests such as compaction, falling head permeability, swelling, unconfined compression and shear strength tests were conducted to select an optimum mixture which eventually led to a recommendation to select an optimum bentonite-sand mixture possessing a bentonite content of 30 % for the isolation of underground waste disposal facilities. Bentonite-sand seal design was performed for the optimum seal selected as a function of the axial stress applied to the seal and seal length-to-radius ratio.

Evaluation of a compacted bentonite/sand seal for underground waste repository isolation Akgün, Haluk; AKTÜRK, ÖZGÜR (Springer Science and Business Media LLC, 2006-06-01) This study investigates the performance of an optimum compacted bentonite/sand mixture seal for the isolation of underground waste repositories. Engineering geological tests such as compaction, flow, swelling, mechanical and shear strength tests have been conducted to select an optimum mixture and to recommend a stable bentonite/sand seal length-to-radius ratio (L/a) as far as the factor of safety (F) is concerned. The results of the compaction permeameter tests led to a recommendation to select an optimum ...
Composite landfill liner design with Ankara clay, Turkey Met, İlker; Akgün, Haluk (Springer Science and Business Media LLC, 2005-04-01) This study presents an overview of the geotechnical properties of the clayey soils, referred to as "Ankara clay", at two sites of the Ankara region in an attempt to design a landfill profile composed of a high density polyethylene (HDPE) geomembrane/clay composite liner through the Hydrologic Evaluation of Landfill Performance (HELP) model and the Water Balance Method. The geotechnical properties of the landfill layers along with the water balance factors (i.e., evapotranspiration, precipitation, temperatur...
Comparison of anaerobic acrylic acid biotransformation in single- and two-stage pH-stat completely stirred tank reactor systems Demirer, Göksel Niyazi; Speece, RE (Wiley, 2000-01-01) Performance of single- and two-stage pH-stat completely stirred tank reactor (CSTR) systems for anaerobic acrylic acid biotransformation was investigated and compared. In the experiments, acetate was added with acrylic acid. Acetate concentration in both single- and two-stage reactors was continuously maintained at a nonlimiting concentration of 2000 +/- 200 mg/L. using a computer-controlled pH-stat system to allow observation of the effect of acrylate biotransformation on the more sensitive methanogenic st...
PHPA as a Frictional Pressure Loss Reducer and Its Pressure Loss Estimation Ozbayoglu, M. E.; Ercan, C. (Informa UK Limited, 2010-01-01) This article analyzes the performance of a liquid polymer emulsion containing partially hydrolyzed polyacrylamide/polyacrylate (PHPA) copolymer as a circulating system pressure loss (drag) reducer. Straight cylindrical pipe flow experiments were performed at different concentrations of solutions for measuring frictional pressure losses. Comparison of measured and theoretical frictional pressure loss values showed that as the PHPA concentration increased, considerable drag reduction (as high as 60%) was achi...
Assessment of discontinuous rock slope stability with block theory and numerical modeling: a case study for the South Pars Gas Complex, Assalouyeh, Iran AZARAFZA, Mohammad; ASGHARI-KALJAHI, Ebrahim; Akgün, Haluk (Springer Science and Business Media LLC, 2017-06-01) In this study, a geotechnical model has been used to analyze the stability of a discontinuous rock slope. The main idea behind block theory is that it disregards many different combinations of discontinuities and directly identifies and considers critical rock blocks known as "key blocks". The rock slope used as a case study herein is situated in the sixth phase of the gas flare site of the South Pars Gas Complex, Assalouyeh, Iran. In order to analyze the stability of discontinuous rock slopes, geotechnical...
