Abstract
The paper presents results of a laboratory study that investigated mechanical durability of expanded shale lightweight aggregate. Large-size, one-dimensional cyclic compression and direct shear tests were performed to investigate particle breakage under these loading conditions. The results obtained are compared with the data reported by other researchers. The results indicate that the expanded shale lightweight aggregate experiences only a minor amount of particle breakage under one-dimensional compression and direct shear type of loadings.
