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. ... -
Improving daily streamflow forecasts in mountainous Upper Euphrates basin by multi-layer perceptron model with satellite snow products
(Elsevier Science BV, 2016)This paper investigates the contribution of Moderate Resolution Imaging Spectroradiometer (MODIS) satellite Snow Cover Area (SCA) product and in-situ snow depth measurements to Artificial Neural Network model (ANN) based ... -
Basin/Reservoir System Integration for Real Time Reservoir Operation
(Springer, 2016)This paper demonstrates the basin/reservoir system integration as a decision support system for short term operation policy of a multipurpose dam. It is desired to re-evaluate and improve the current operational regulation ... -
Comparison of Different Reservoir Models for Short Term Operation of Flood Management
(Elsevier Science BV, 2016)Short-term operation of reservoir systems is challenging due to conflicting objectives and constraints as well as the need for taking robust decisions in real-time. This study compares simulation and optimization based ... -
Electricity generation from existing multipurpose dams in Turkey
(Multi Science Publ Co LTD, 2005)The aim of this article is to investigate the hydropower potential of multipurpose dams constructed with the purpose of supplying irrigation, domestic water supply, flood control, navigation, recreation, sanitation, and ... -
Contribution of Built Environment Design Elements to the Sustainability of Urban Renewal Projects: Model Proposal
(Asce-Amer Soc Civil Engineers, 2019)Urban renewal aims to solve the problems caused by unplanned urbanization and urban aging, and it presents a significant opportunity to create sustainable urban areas in Turkey, where a major urban renewal movement was ... -
Monthly streamflow estimation using wavelet-artificial neural network model: A case study on Camlidere dam basin, Turkey
(Elsevier Science BV, 2017)Data driven techniques have become well-known application in hydrology in which physical processes are highly nonlinear. They require detailed analyses of different input combinations, selecting the appropriate model ... -
Streamflow Forecasting Using Different Neural Network Models With Satellite Data for a Snow Dominated Region in Turkey
(Elsevier Science BV, 2016)Data driven models such as Artificial Neural Networks (ANNs) became a very popular tool in hydrology for a long time, especially in rainfall-runoff modelling. However, it does not have common usage in mountainous catchments, ... -
Application of Different Rehabilitation and Strengthening Methods for Insufficient RC Beam-Column Joints
(Trans Tech Publications LTD, 2013)Earthquake is one of the most destructive natural disasters that cause loss of life and property in the earthquake prone regions. Unsuitable soil conditions, inadequate material properties and deficiencies in the structural ... -
Optimum Design of Conventional Sfrcs and Their Performance Classes
(Czech Technical University Prague, 2011)For determining the performance classes of steel fiber reinforced concretes (SFRCs), their equivalent flexural strengths were investigated according to both Serviceability Limit State (SLS) and Ultimate Limit State (ULS). ... -
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 ... -
