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 ... -
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 ... -
The effects of filler glasses on mechanical properties of concrete
(Trans Tech Publications LTD, 2004)According to the relevant literature, the utilisation of different kind of glasses in concrete introduces positive effect on the mechanical behaviour. The factor affecting physical and mechanical properties and chemical ... -
Mechanical and microstructural properties of heated and polluted kaolinite and bentonite
(Trans Tech Publications LTD, 2004)High temperatures and pollution due to the storage of nuclear wastes in deep soil influence the mechanical properties and microstructure of kaolinite and bentonite. In this study, 0.5 N CaCl2 and 2000 ppm ZnCl2 solutions ... -
Utilization of ceramic wastes in the construction sector
(Trans Tech Publications LTD, 2004)Ceramic wastes causing a serious problem are polluting the environmental problem in Eskisehir Region, Turkey. In this paper, were studied three wastes, ceramic mud wastes (CMW), crushed ceramic tile wastes (CCTW) and ceramic ... -
A Recommended Neural Trip Distribution Model
(Hong Kong Universityersity Science &Technology, 2005)In this study, it is aimed to develop an approach for the trip distribution element which is one of the important phases of four-step travel demand modelling. The trip distribution problem using back-propagation artificial ... -
Effect of sulfates on the physical properties of Portland cement mortars
(International Society Offshore& Polar Engineers, 2005)Concrete is produced by mixing cement, aggregate and water. The aggregates are inert materials and the chemical reactions take place between cement and water. Therefore, the properties of mixing water are very important ... -
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. ... -
Conceptual framework for capturing tacit knowledge in construction projects
(Taylor & Francis LTD, 2006)The importance of knowledge management is increasingly being recognised in almost every industry Managing knowledge effectively is critical to the survival and advance of a company especially in project-based industries ... -
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 ... -
Modeling of rainfall-runoff relationship at the semi-arid small catchments using artificial neural networks
(Springer-Verlag Berlin, 2006)The artificial neural networks (ANNs) have been applied to various hydrologic problems in recently. In this paper, the artificial neural network (ANN) model is employed in the application of rainfall-runoff process on a ... -
Accuracy assessment of MODIS daily snow albedo retrievals with in situ measurements in Karasu basin, Turkey
(John Wiley & Sons LTD, 2006)Over the ablation period of 2004, daily snow albedo values retrieved from the moderate-resolution imaging spectroradiometer (MODIS) Terra were compared with ground-based albedo measurements. Two data sets are used for this ... -
Web-based subcontractor evaluation system
(Taylor & Francis LTD, 2006)One of the most important phases in the construction industry is the bidding process. During the bidding process, selecting the most appropriate subcontractor for the relevant works is highly critical. In order to select ... -
Polypropylene fiber modification of asphalt by using mechanical and optical means
(Crc Press-Taylor & Francis Group, 2009)In this study, first of all, the physical and chemical effects of polypropylene fiber modification on bitumen samples were investigated. Then, the amount of "optimum" polypropylene fibers was determined. In order to determine ... -
Information Technology Usage Impacts on Construction Projects' Success
(Vilnius University, 2010)Information technology (IT) plays an important role for improving business processes and has significant effects on project time, cost and quality in the construction industry. Effective use of IT may increase construction ... -
Evaluating the utility of the ANSA blended snow cover product in the mountains of eastern Turkey
(Taylor & Francis LTD, 2010)Snow-covered area depletion curves represent a key input for snow run-off melting models, e.g. the snowmelt run-off model (SRM). SRM is a degree-day-based model for daily run-off simulations and forecasts in mountainous ...
