In this study, the crushed stone potential and usage areas of the formations cropped out around Elazığ was investigated. For this purpose, aggregate samples were prepared from block samples collected from Keban Metamorphites, Kömürhan Ophiolites, Elazığ Magmatics, Harami Formation, Maden Complex, Seske Formation, Kırkgeçit Formation and Karabakır Formation and experimental studies were conducted. The results obtained from the experiments were compared with the limit values given in the technical specifications and standards and the usability of the rocks as concrete aggregate, ballast and road superstructure material was determined. The results of this study show that the andesites of Elazığ Magmatics, the limestones of Harami Formation, the basalts of Maden Complex and the limestones of Kırkgeçit Formation can be used as concrete aggregate. The andesites of Elazığ Magmatics are suitable for use as railway ballast. Also, the limestones of Harami, Seske and Kırkgeçit formations and the basalts of Maden Complex are usable in all layers of the road superstructure. [ABSTRACT FROM AUTHOR]

Bu çalışmada, Geç Kretase yaşlı Elazığ Magmatitleri’ne ait bazaltların kimyasal, fiziksel ve mekanik özellikleri incelenmiş ve bazaltların kırmataş olarak kullanılabilirliği araştırılmıştır. Çalışma arazi ve laboratuvar çalışmaları olmak üzere iki aşamada gerçekleştirilmiştir. Arazi çalışmaları sırasında, bazaltların ayrışma derecesi, süreksizlik aralığı ve RQD değerleri belirlenmiş, laboratuvar çalışmaları için 7 farklı lokasyondan blok bazalt örnekleri derlenmiştir. Bazaltların kimyasal, fiziksel ve mekanik özelliklerini belirlemek için ISRM, ASTM, BS, CA ve TS standartlarına göre laboratuvar deneyleri gerçekleştirilmiştir. Arazi ve laboratuvar ve çalışmalarından elde edilen sonuçlara göre bazaltların beton agregası, mıcır, balast, tahkimat malzemesi ve anroşman olarak kullanılabilirliği irdelenmiştir. Laboratuvar deney sonuçları, bazaltların beton agregası, mıcır, balast ve tahkimat malzemesi olarak kullanılabileceğini göstermektedir. Ancak, bazaltlar yavaş reaktif özelliktedir ve alkali silis reaksiyonunun oluşumuna engel olmak için beton üretiminde düşük alkaliniteli çimento ve puzzolanik katkı maddeleri kullanılmalıdır. Bazaltlar, içerdikleri eklemlerin ara uzaklığı düşük olduğu için anroşman olarak kullanılmaya uygun değildir.

In this study, chemical and geomechanical properties of basalts of Late Cretaceous aged Elazig Magmatits were examined and the usability of basalts as crushed stone was investigated. Research was carried out in two stages including field and laboratory studies. During the field studies, weathering degree of basalts, joint spacing and RQD values were determined and blocks of basalt samples were collected from 7 different locations. Laboratory tests were carried out in accordance with the ISRM, ASTM, BS, CA and TS standards to determine physical, chemical and mechanics properties of basalts. Usability of basalts as concrete aggregate, gravel, ballast, support material and armourstone were examined using results obtained from laboratory tests and field investigations. Laboratory test results show that basalts can be used as concrete aggregate, gravel, balast and support material. However, the basalts are slow reactive characteristic and low alkalinity cement and pozzolanic additives should be used in concrete production to prevent alkali-silica reaction. The basalts do not have suitable properties for use as armourstone since spacing of joints are closed. [ABSTRACT FROM AUTHOR]
