Jan 01, 2007 Consequently, the size and mechanical properties of calcite generate two very different failure mechanisms in limestone and marble. In the case of granite, quartz and feldspar grains do not deform plastically at low confinement, and crack propagation continues in the direction of the applied load (Gramberg, 1989). Hence, granite and marble ...

Sand Media Specifications

Media with small grain size slow the water movement and increase the chance of clogging. The effective size (D 10) and uniformity coefficient (Uc) are the principal characteristics of granular media treatment systems. The ideal sand media for intermittent sand filters is a coarse sand with an effective size between 0.3 mm and 0.5 mm.
