High-Temperature Release of SO2 from Calcined Cement Raw Materials

During combustion of alternative fuels in the material inlet end of cement rotary kilns, local reducing conditions may occur and cause reductive decomposition of sulfates from calcined cement raw materials. Decomposition of sulfates is problematic because it increases the gas-phase SO2 concentration, whichmay cause deposit formation in the kiln system. In this study, the release of sulfur from ...

Sulfur Release from Cement Raw Materials during Solid Fuel Combustion

During combustion of solid fuels in the material inlet end of cement rotary kilns, local reducing conditions can occur and cause decomposition of sulfates from cement raw materials. Decomposition of sulfates is problematic because it increases the gas-phase SO2 concentration, which may cause deposit formation in the kiln system. SO2 release from cement raw materials during combustion of solid f...

Characterisation of Biologically Pretreated Raw Materials for Biopulping Process

Biopulping, the treatment of wood chips by white rot fungi and subsequent chip refining is envisioned as a method for saving energy and making a stronger paper product. The present study aims to find suitability of two fungal isolates Phellinus pectinatus and Daedaleopsis confragosa for the process of biopulping and the characteristion of the biologically pretreated raw materials for biopulping...

Blending Different Fineness Cements to Engineer the Properties of Cement-Based Materials

Concretes are designed to fulfill specific engineering requirements, commonly exemplified by slump, unit weight, and compressive strength. One source of untapped potential for varying engineering properties of hardened concrete is the variation of the cement particle size distribution. In this study, the performance of cements prepared by blending a coarse ASTM C150 Type I/II and a fine Type II...
