An extended pressure application for transient seepage problems with a free surface
(Begell House Inc, 2005)In this paper, a new finite-difference-solution technique for solving transient seepage problems with an unknown free sur ace has been proposed. The governing finite-difference equations were derived using flux conservation ... -
An investigation of waste foundry sand in asphalt concrete mixtures
(SAGE Publications LTD, 2006)A laboratory study regarding the reuse of waste foundry sand in asphalt concrete production by replacing a certain portion of aggregate with WFS was undertaken. The results showed that replacement of 10% aggregates with ... -
Turkey's non-fossil energy sources and positive expectations in the next decades
(Taylor & Francis Inc, 2005)According to some projections, Turkey's primary energy demand is expected to increase four times its 1998 value in the next 20 years. Turkish gas demand is expected to increase more than five folds in 2010 and eight times ... -
Mechanical evaluation of asphalt-aggregate mixtures prepared with fly ash as a filler replacement
(Natl Research Council Canada-N R C Research Press, 2008)The objective of this study is to investigate the effect of fly ash as a filler replacement on the mechanical properties of asphalt-aggregate mixtures. Utilization of fly ash, which is the by-product of coal-fired power ... -
The lower employment of women in Turkish construction sector
(Pergamon-Elsevier Science LTD, 2004)More than half of the population of Turkey is women. However, although there is an increase in the number of population, they have still been under-represented in the labour force. The conceptual and empirical elements ... -
The effect of polypropylene fibers on asphalt performance
(Pergamon-Elsevier Science LTD, 2008)Polypropylene fibers are extensively used in civil engineering applications for many years. These fibers are used in concrete as a three-dimensional secondary reinforcement. Due to adhesion between polypropylene fibers and ... -
Effects of elevated temperatures on properties of concrete
(Elsevier Sci LTD, 2007)Concrete material in structures is likely exposed to high temperatures during fire. The relative properties of concrete after such an exposure are of great importance in terms of the serviceability of buildings. This paper ... -
The current status and future opportunities of hydroelectricity
(Taylor & Francis Inc, 2007)This study presents the status of and prospects for the current state of small hydropower technologies used to produce electricity and assesses their future prospects. The hydropower currently provides about 20% of the ... -
A comparative study on the interpretation of concrete core strength results
(Thomas Telford Publishing, 2006)Cores measuring 94 mm and 144 mm in diameter and having length-to-diameter ratios of 2-0, 1.0 and 0.75 were removed from beam specimens produced from different concrete mixtures. Standard cubes and cylinders were also ... -
Effects of Crumb Rubber Size and Concentration on Performance of Porous Asphalt Mixtures
(Hindawi Publishing Corporation, 2013)The purpose of this study is to investigate the effect of size distribution and concentration of crumb rubber on the performance characteristics of porous asphalt mixture. The recycling of scrap tires in asphalt pavements ... -
The mathematical modelling of total nitrogen contamination transport via groundwater from a sugar factory in Eskisehir, Turkey
(Inderscience Enterprises LTD, 2003)In this study, mathematical modelling of the total nitrogen contamination transport in a porous medium was evaluated in order to determine the potential groundwater pollution caused by a sugar factory in the Eski(.)ehir ... -
Some factors influencing effect of core diameter on measured concrete compressive strength
(Amer Concrete Inst, 2007)Various concrete mixtures were produced using crushed limestone and river gravels with four different maximum sizes of 10, 15, 22, and 30 mm (0.39, 0.59, 0.87, and 1.18 in.). The 28-day cube strength of concrete mixtures ... -
Mapping field surface soil moisture for hydrological modeling
(Springer, 2007)Soil moisture is a major control variable on hydrological processes both at the storm event scale and in the long term. The aggregate effect on the mean water balance over an area can be quantified successfully using ... -
Web-based quality control of ready mixed concrete
(Pergamon-Elsevier Science LTD, 2007)The ready mixed concrete industry is an important part of today's construction business environment. This industry provides the required quality of concrete used in construction works. The production of this concrete has ... -
Sustainable development of small hydropower plants (SHPs)
(Taylor & Francis Inc, 2004)The aim of this article is to investigate the small hydropower plants (SHPs) in Turkey. Total hydropower potential of Turkey is annually 433,000 GWh. Almost 50% of the total potential is technically exploitable and 29% ... -
Use of natural zeolites as a landfill liner
(I W M Business Services LTD, 2003)The purpose of this study is to investigate certain features of a novel material proposed to serve as an impervious liner in landfills. Various ratios of bentonites and zeolites (B/Z) compacted at optimum water content ... -
Impact of cyclic wetting-drying on swelling behavior of lime-stabilized soil
(Pergamon-Elsevier Science LTD, 2007)In this study, the impact of cyclic wetting and drying on swelling behavior of lime-stabilized clayey soils has been investigated. Swelling potential and swelling pressure tests have been carried out on soil mixtures with ... -
The use of kaolinite/zeolite mixtures for landfill liners
(Inderscience Enterprises LTD, 2005)The use of kaolinite/zeolite mixtures as alternative landfill materials has been studied. The ratios of kaolinite/zeolite used were K/Z = 0.1, K/Z = 0.2 and K/Z = 0.3. To determine the geotechnical and physicochemical ... -
Optimal polypropylene fiber amount determination by using gyratory compaction, static creep and Marshall stability and flow analyses
