Use of zeolite, coal bottom ash and fly ash as replacement materials in cement production

Yılmaz, Kemalettin; Sümer, Mensur (PERGAMON-ELSEVIER SCIENCE LTD, 2004)

In this research, the effects of zeolite, coal bottom ash and fly ash as Portland cement replacement materials on the properties of cement are investigated through three different combinations of tests. These materials are ...
Use of Zeolite Coal Bottom ash and Fly ash Replacement Materials in Cement Productıon

Sümer, Mensur (2004)
Diagnosis of the transition from rock soil in a granodiorite

Arel, Ersin (ASCE-AMER SOC CIVIL ENGINEERS, 2004)

This paper describes an attempt to develop a method to define when granodiorite loses its properties as a rock and transforms into soil material. The research program approached the problem from a mechanistic point of view ...
Evaluation of Water Quality and Supplies by Using Geographical Information Systems in Istanbul

Güler, Hakan (2004)
Use of Zeolite Coal Bottom ash and Fly ash Replacement Materials in Cement Productıon

Sümer, Mensur (2004)
Subsurface characterization at ground failure sites in adapazari, Turkey

Bol, Ertan (ASCE-AMER SOC CIVIL ENGINEERS, 2004)

Ground failure in Adapazari, Turkey during the 1999 Kocaeli earthquake was severe. Hundreds of structures settled, slid, tilted. and collapsed due in pail to liquefaction and ground softening. Ground failure was more severe ...
Forecasting based on neural network approach of solar potential in Turkey

Çağlar, Naci (PERGAMON-ELSEVIER SCIENCE LTD, 2005)

As Turkey lies near the sunny belt between 36 and 42 degrees N latitudes, most of the locations in Turkey receive abundant solar energy. Average annual temperature is 18-20 degrees C on the south coast, falls down to 14-16 ...
Design of a short tensile coupon for fiber reinforced plastic using artificial neural networks

Sarıbıyık, Mehmet; Çağlar, Naci; Fırat, Seyhan (WALTER DE GRUYTER GMBH, 2005)

The measurement of the mechanical properties of Fibre Reinforced Plastic (FRP) material is necessary for numerical structural analysis and design. The mechanical properties of the FRP materials may be determined by specific ...
Investigation of ground vibrations induced by moving loads

Çelebi, Erkan (ELSEVIER SCI LTD, 2005)

The objective of this work indicates and discusses two mathematical models and numerical techniques for solving problems associated with wave propagation in the track and subsoil due to the passage of a train. The Thin ...
A reply to the discussion by H. Un of the paper "Use of zeolite, coal bottom ash and fly ash as replacement materials in cement production" [Cem. Concr. Res. 34 (5) (2004) 731-735]

Sümer, Mensur; Yılmaz, Kemalettin (PERGAMON-ELSEVIER SCIENCE LTD, 2005)
Dissolved oxygen estimation using artificial neural network for water quality control

Şengörür, Bülent; Doğan, Emrah; Köklü, Rabia (PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2006)

Dissolved oxygen (DO) is one of the key parameters when analyzing river water quality. Correct estimation of DO being carried by a river is very important for water quality control. DO is affected by lots of variables such ...
The effectiveness of wave barriers on the dynamic stiffness coefficients of foundations using boundary element method

Çelebi, Erkan; Fırat, Seyhan; Çankaya, İlyas (ELSEVIER SCIENCE INC, 2006)

A comprehensive numerical investigation has been carried out to indicate the influence of wave barriers on the complex dynamic stiffness coefficients of the surface supported foundations under dynamic loads. In the considered ...
Three-dimensional modelling of train-track and sub-soil analysis for surface vibrations due to moving loads

Çelebi, Erkan (ELSEVIER SCIENCE INC, 2006)

Two mathematical models and numerical techniques for solving problems associated with the wave propagation in a track and an underlying soil due to passing trains are presented and compared. For the analysis, the thin layer ...
I-section flange compactness under minor axis flexure

Aktaş, Muharrem (TECHNO-PRESS, 2006)

The present paper hopes to elucidate the problem of determining if a given I-shaped cross-section is properly proportioned to accommodate sufficient plastic hinge rotation capacity to facilitate the redistribution of moments ...
Predicting the compressive strength and slump of high strength concrete using neural network

Çağlar, Naci (ELSEVIER SCI LTD, 2006)

High Strength Concrete (HSC) is defined as concrete that meets special combination of performance and uniformity requirements that cannot be achieved routinely using conventional constituents and normal mixing, placing, ...
Lateral load estimation from visco-plastic mud-flow around cylindrical row of piles
