Web-Based Contractor Evaluation System for Mass-Housing Projects in Turkey
(Vilnius Gediminas Tech University, 2012)Determining the most appropriate contractor for a construction project is a highly critical issue. Selecting the right contractor for the right job can significantly influence the overall project performance. In the selection ... -
Use of petroleum-contaminated drilling wastes as sub-base material for road construction
(Munksgaard Int Publ LTD, 2000)In this study, petroleum-contaminated drilling wastes were stabilized by mixing pozzolanic fly ash, lime and cement with them so they could be used as sub base materials for road construction. This stabilization produced ... -
Ground water contaminant transport by nondivergence-free, unsteady and nonstationary velocity fields
(Elsevier Science BV, 2006)Pore flow velocity is assumed to be a nondivergence-free, unsteady, and non-stationary random function of space and time for ground water contaminant transport in a heterogeneous medium. The laboratory-scale stochastic ... -
The effect of non divergence-free velocity fields on field scale ground water solute transport
(Springer, 2006)Solute plume subjected to field scale hydraulic conductivity heterogeneity shows a large dispersion/macrodispersion, which is the manifestation of existing fields scale heterogeneity on the solute plume. On the other hand, ... -
Transport modelling of copper contamination in groundwater caused by a wood preservation plant
(Iwa Publishing, 2005)Contaminants can adhere to soil and subsequent rainfall can leach the adhered contaminant into groundwater. Transport models can determine the main features of contaminant and carrier transport in groundwater systems, and ... -
The use of waste materials in asphalt concrete mixtures
(I W M Business Services LTD, 2003)The purpose of this study was to investigate (a) the effects of rubber and plastic concentrations and rubber particle sizes on properties of asphalt cement, (b) on properties of asphalt concrete specimens and (c) the effects ... -
Determination of soil hydraulic properties using pedotransfer functions in a semi-arid basin, Turkey
(Copernicus Gesellschaft Mbh, 2004)Spatial and temporal variations in soil hydraulic properties such as soil moisture 0(h) and hydraulic conductivity K(theta) or K(h), may affect the performance of hydrological models. Moreover. the cost of determining soil ... -
On the using cumulant expansion method and van Kampen's lemma for stochastic differential equations with forcing
(Springer, 2013)Second-order exact ensemble averaged equation for linear stochastic differential equations with multiplicative randomness and random forcing is obtained by using the cumulant expansion ensemble averaging method and by ... -
Point-scale energy and mass balance snowpack simulations in the upper Karasu basin, Turkey
(John Wiley & Sons LTD, 2006)Since snowmelt runoff is important in the mountainous parts of the world, substantial efforts have been made to develop snowmelt models with many different levels of complexity to simulate the processes at the ground ... -
Electricity production opportunities from multipurpose dams (case study)
(Pergamon-Elsevier Science LTD, 2007)The hydropower is the leading source of renewable energy. It provides more than 97% of all electricity generated by renewable sources. The main advantage of hydro systems is elimination of the cost of fuel. Hydropower on ... -
Turkey's water resources and hydropower potential
(Sage Publications Inc, 2005)The aim of this paper is to investigate water resources in Turkey. Annual rainfall varies from 220 torn to 2500 mm with an average of 643 mm, which means total volume of 501 km(3) and average annual potential of surface ... -
The influence of environmental pollution on cyclic swell and shrink behavior of Na-bentonite clay
(Trans Tech Publications LTD, 2004)This paper investigates the environmental pollution effects such as saline water, kerosene and sanitary leachate of cyclic wetting and drying on swell and shrink behaviour of compacted Na-bentonite clay. While the distilled ... -
Utilisation of waste bricks as cement replacement material in concrete production
(Trans Tech Publications LTD, 2004)Waste clay bricks constitute one of the important groups of the waste materials that cause environmental problems unless the proper use of these materials is found. In this study, the clay brick wastes obtained from a ... -
Concrete with recycled aggregate
(Trans Tech Publications LTD, 2004)Reuse of hardened concrete rubbles caused by the demolition of concrete structures has recently become possible in construction industry. The utilisation of these materials M concrete production may provide two main benefits; ... -
Characterisation of polluted clay-zeolite landfill liner materials using scanning electron microscopy
(IOP Publishing LTD, 2004)A landfill liner act as a barrier to minimize the migration of leachates in waste containment systems. Thus, proper management of leachates is important to minimize the risk of contamination for groundwater and subsoil. ... -
A preliminary study into microstructural characterisation of the river Porsuk sediments, Turkey
(IOP Publishing LTD, 2004)This study reports the preliminarily scientific data on some of the morphology and surface features of the polluted, soft organics, bottom river sediments collected from depths of 0-40 cm at representative sites along the ... -
Electron microscopy studies of municipal sludge contaminated marine clay
(IOP Publishing LTD, 1999)The effects of municipal sludge on physico-chemical and microstructure of laboratory prepared marine clay sediments were investigated. Experiments were conducted on artificially prepared marine sediments to investigate ... -
Effects of sulfates on strength of Portland cement mortars
(International Society Offshore& Polar Engineers, 2005)Concrete is a composite material which is produced by mixing cement, aggregate, water and if required admixtures. The quality of mixing water plays an important role in the mechanical behavior of hardened mortar and concrete. ... -
Retained properties of concrete exposed to high temperatures: Size effect
(John Wiley & Sons LTD, 2009)Concrete as a construction material is likely exposed to high temperatures during fire. The retained properties of concrete after such exposures are still of great importance in terms of the serviceability of structures. ...
