Statistical distributions of in situ microcore concrete strength
(Elsevier Sci LTD, 2012)Quality control processes require accurate knowledge of in situ compressive strength of concrete. The most widely accepted method of determining the compressive strength of concrete in existing structures is to test core ... -
The effect of heat-treated boron derivative waste at 600 degrees C on the mechanical and microstructural properties of cement mortar
(Elsevier Sci LTD, 2017)Turkey holds 73% of the world's boron deposits. 25.3% of the total deposits are tincal ore and located in Eskisehir Kirka region. During the production of 1 million tons of borax pentahydrate (Na2O center dot 2B(2)O(3)center ... -
Alternative Electric Energy Source Selection in Construction Projects: A Case Study in Turkey
(Int Assoc Engineers-Iaeng, 2011)The objectives of this study are to find the best way to calibrate data that are collected from the energy maps of Turkey and take advantage of alternative electric energy source in construction projects. To achieve these ... -
Determination of Concrete Strength By Using Small Diameter Cores and Microcores
(Novpress Sro, 2011)Strength of concrete is an important property for the quality of concrete. Compression testing of cores drilled from hardened concrete is a widely accepted method of strength determination. Estimation of concrete strength ... -
Monthly streamflow forecasting using continuous wavelet and multi-gene genetic programming combination
(Elsevier Science BV, 2018)Streamflow is an essential component of the hydrologic cycle in the regional and global scale and the main source of fresh water supply. It is highly associated with natural disasters, such as droughts and floods. Therefore, ... -
Leaching of trace metals from high carbon fly ash stabilized highway base layers
(Elsevier Science BV, 2012)Fly ash produced by power plants in the United States occasionally contains significant amounts of unburned carbon due to the use of low nitrogen-oxide and sulphur-oxide burners in recent years. This ash cannot be reused ... -
Long-term spatiotemporal trend analysis of precipitation and temperature over Turkey
(Wiley, 2018)Monthly precipitation and temperature data for Turkey were obtained from the Climate Research Unit Time Series (CRU TS V3.23) dataset (1901-2014) and analysed. The records of 81 grids, each located in a province, were ... -
Streamflow Forecasting Using Four Wavelet Transformation Combinations Approaches with Data-Driven Models: A Comparative Study
(Springer, 2018)This study investigates the use of wavelet transformation (WT) as preprocessing tool in data-driven models (DDMs) for forecasting streamflow 7days ahead. WT used are Continuous wavelet transformation (CWT), discrete wavelet ... -
Forecasting Daily Streamflow for Basins with Different Physical Characteristics through Data-Driven Methods
(Springer, 2018)Modelling streamflow is essential for activities, such as flood control, drought mitigation, and water resources utilization and management. Artificial neural network (ANN), adaptive neuro-fuzzy inference system (ANFIS), ... -
Utilization of sepiolite materials as a bottom liner material in solid waste landfills
(Pergamon-Elsevier Science LTD, 2014)Landfill bottom liners are generally constructed with natural clay soils due to their high strength and low hydraulic conductivity characteristics. However, in recent years it is increasingly difficult to find locally ... -
Sepiolite as an alternative liner material in municipal solid waste landfills
(Asce-Amer Soc Civil Engineers, 2008)Compacted clay has traditionally been used as a lining material in municipal solid waste landfills. However, natural clays may not always provide good contaminant sorption properties. One alternative material that is ... -
Structural behavior of concrete filled steel tubular sections (CFT/CFSt) under axial compression
(Elsevier Sci LTD, 2014)In this study, compressive strength, modulus of elasticity and steel tensile coupon tests are performed to determine material properties. Sixteen hollow cold formed steel tubes and 48 concrete filled steel tube specimens ... -
Drainage and Mechanical Behavior of Highway Base Materials
(Asce-Amer Soc Civil Engineers, 2014)The mechanical and drainage properties of graded aggregate base (GAB) materials used in mechanistic pavement design are the level one inputs. Several highway agencies need an evaluation of the stiffness and drainage ... -
Evaluation of Probabilistic Streamflow Forecasts Based on EPS for a Mountainous Basin in Turkey
(Elsevier Science BV, 2016)When designing water structures or managing a watershed it is a challenging task to determine the response of a basin to storm and/or snowmelt. In this study, the Upper Euphrates Basin (10,275 km(2) area and elevation range ... -
Determination of elasticity modulus of low strength concrete and its effect on the risk assessment results by DSVB
(Gazi University, Fac Engineering Architecture, 2017)Turkey is frequently exposed to destructive earthquakes causing loss of lives and property. There are many factors that affect the seismic vulnerability of existing buildings. Poor concrete quality is a major and widespread ... -
Effects of Compaction Method and Aggregate Properties on Mechanical Behavior of Granular Base Layer
