A series of undrained monotonic and cyclic triaxial tests were performed on silica sand at two initial densities and different confining pressures from 0.1 to 5 MPa to investigate their shear response and crushing behaviour. The influence of particle crushing on the undrained shear strength and pore-water pressure was examined. To …

This paper demonstrates the latest developments in particle-scale modelling of a clay. It shows that by creating an initial sample of platelets featuring aggregated stacks, excellent macroscopic behaviour is achieved. This approach is justified by examining SEM images of clay slurries, and is consistent with the behaviour of real clays. The use of …

Silica is a naturally occurring substance found in certain types of sand, clay and rock. However, many construction materials, ceramics and industrial sand contain crystalline silica particles, including mortar and concrete. Workers in the construction, mining, steelworking and extraction industries are among those most at risk.

Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore. These ingredients, when heated at high temperatures form a rock-like substance that is ground into the fine powder that we commonly think of as cement.
