Predicting the Los Angeles abrasion loss of rock aggregates from the uniaxial compressive strength

Los Angeles abrasion, Uniaxial compression, and porosity tests were performed on 35 different rock types collected from different areas of Turkey, nine of which were igneous, eleven of which were metamorphic and fifteen of which were sedimentary. To investigate the possibility of predicting the Los Angeles (LA) abrasion loss from the uniaxial compressive strength (UCS), the results of the tests were analyzed using regression analysis. A good correlation between L.A. abrasion loss and UCS was found. In addition, it was seen that when the rocks were classified into classes according to porosity, the correlation coefficients were increased. Concluding remark is that derived equations can reliably be used for the prediction of L.A. abrasion loss from the UCS. (c) 2007 Elsevier B.V All rights reserved.
