Evaluation of selected basalts from Nigde, Turkey, as a source of concrete aggregate
Basaltic rocks have been used extensively as engineering materials including aggregates for portland cement concrete and asphaltic concrete, rock fill for dams and breakwaters, material for railroad ballast and highway base courses. They show a variety of textural and mineralogical characteristics that may affect their physico-mechanical properties as well as their use as construction material. The study presented was carried out on basalts that are widespread in the Middle Anatolian Region, TR, and that comprise the major source of local crushed rock aggregates. To determine the suitability of the basalts as alternative aggregate resource, Early Quaternary Melendiz volcanites, Quaternary Karatas volcanites and Igredag basalts were selected from the Nigde Region, TR. The samples were collected as being representative of 11 different types of basalt. The physico-mechanical properties of the basalts of different compositions and textures, and the properties of their aggregates were determined. The results are compared with the typical acceptance limits in international usage. Although olivine basalts have better aggregate quality compared to other basalts, most of the basalts were found to be suitable for production of crushed rock aggregates for concrete production.
