In recent years, the usage of aggregate materials has increased both in Turkey and the entire world. It can be said that the main reason of this rise is the population growth together with the demand towards the more qualitative life. Therefore, the usability of some aggregate materials was investigated in the present paper. The properties of Los Angeles abrasion resistance, freezing-thaw resistance, slake durability strength and frost resistance of basalt and andesite samples obtained from Karaman and Ankara regions were studied at the first stage. In the second order, the grindability performance of these materials was also determined from the discontinuous grinding tests and the obtained results were correlated. Whereas the Los Angeles resistance of the basalt sample was higher than the andesite sample, the mass losses after the freezing-thaw and the frost tests for the andesite sample were superior. Both of the basalt and andesite samples were classified as ‘very high’ for their slake durability strength (Id-2) values. The material percentage of the andesite sample, which is passing through the sub-size ( %90) was greater than the value obtained for the basalt sample during the same grinding time. The resistance to the crushing process was obtained to be maximum at -850+600 µm of feed size for the basalt and the andesite samples. |
