ALKALI SILICA REACTION OF BOF AND BFS WASTES COMBINATION IN CEMENT

Özkan, Ömer; Sarıbıyık, Mehmet (VILNIUS GEDIMINAS TECH UNIV, 2013)

This study reports the results of an experimental study conducted to determine composite cements manufactured with the combination of Basic Oxygen Furnace (BOF) Slag and Blast Furnace Slag (BFS). The overall objective of ...
Cost assessment of construction projects through neural networks

Özkan, Ömer; Gündüz, Mehmet; Demir, İsmail Hakkı (CANADIAN SCIENCE PUBLISHING, NRC RESEARCH PRESS, 2013)

Construction performance parameters have experienced greater international attention and discussion in recent years. In this study, the change in the load-bearing system cost of a reinforced concrete housing estate building ...
Effects of project size and resource constraints on project duration through priority rule-base heuristics

Özkan, Ömer; Gündüz, Mehmet (SPRINGER, 2009)

Priority rules are one of the frequently used methods in project programming with resource-constraints. In this paper, the effects of project size and number of resource constraints on project duration are compared to the ...
Influence of high temperature on the properties of concretes made with industrial by-products as fine aggregate replacement

Özkan, Ömer (ELSEVIER SCI LTD, 2011)

Influence of high temperature on the properties of concrete containing non-ground granulated blast-furnace slag (GBFS) and coal bottom ash (BA) as fine aggregate was presented. Six series of concrete mixtures were prepared ...
Physical and mechanical properties of composite cements

Özkan, Ömer (BAUVERLAG BV GMBH, 2009)

This paper reports on the results of an experimental study conducted to evaluate the physical properties and strength development of composite cements manufactured with a steel slag (SS) and blast-furnace slag (BFS) ...
Prediction of sulfate resistance of cements produced with GBFS and SS additives using artificial neural network

Özkan, Ömer; Yılmaz, Cemal (INDERSCIENCE ENTERPRISES LTD, 2013)

Concrete structures built on sulfate rich soil or wetland, or directly exposed to seawater are subjected to sulfate attack, which might be critical, as the durability of concrete is highly dependent on its resistance against ...
