2. An "S" accompanying an emission factor means that this factor is the weighted average sulfur content of the fuel burned, expressed as a percent. See, for example, SCC 1-01-004-01 on page 14.A-3. If the weighed average sulfur content of the Grade 6 oil burned were three percent (3%), then the SOx emission factor would become 157 x 3,
Bentonite is used as a binder for proper balling of the filter cake particles in to spherical shaped balls with certain compression strength. The bentonite is stored and ground in a Vertical mill by dry grinding process to desired fineness (−200 mesh, 80%). The powdered bentonite is stored for further mixing process.
In this study, bentonite (a naturally occurring pozzolana) was incorporated as a partial replacement (up to 20%) for high-calcium fly ash (HCFA)-based geopolymeric natural aggregate concrete (GNAC) and geopolymeric recycled aggregate concrete (GRAC). The mechanical (compressive strength and splitting tensile strength), durability (chloride migration …

Bentonite is an off-white montmorillonite clay formed from altered volcanic ash. It has a sheet-silicate structure and is especially notable for the way in which it absorbs and loses water and for its base-exchange properties. Sodic bentonite can absorb up to 10 times its own weight in water and can swell to 18 times its dry volume.
