Los Angeles Abrasion Test for Estimating Engineering Index on the Sedimentary Rocks of Kyeongsang Basin
Tuk-Ki Min, Jong-Kyu Moon, Sangil Lee · Journal of the Korean Geotechnical Society · 2007
Los Angeles abrasion loss test has usally been applied to the quarry for the purpose of aggregate hardness estimation. 324 blocks from 25 sites of Kyeongsang basin samples of sedimentary rock were examined and tested in laboratary. This paper found that L. A. abrasion loss test is a good method to estimate engineering index such as uniaxial compressive strength, elastic modulus, indirect tensile strength, point load strength index, Schmidt hammer rebound value of sedimentary rocks with high correlation factor. Engineers will prefer L. A. abrasion loss test to the other one for design and construction as this method is quick and easy.
