the mechanical behaviour of rockfill materials and aggregates depends not only on particle size and compaction, but also on their strength and lithological properties. in this research two types of large triaxial and direct shear tests are performed on rockfill materials. this paper compares the stress-strain behaviour of sandstone and andesibasalt materials in triaxial compression tests (3006...

Concrete-face slabs are the primary anti-permeability structures of concrete-face rockfill dam (CFRD), and resistance face slab concrete to permeability is key factor affecting operation safety CFRDs. Herein, influences five fly ash dosages (namely 10%, 20%, 30%, 40% 50%) on property concretes were investigated. Moreover, difference in caused by dosage variations revealed terms pore structure f...
