The availability of limestone deposits containing lower MgO content (< 2 %) is slowly depleting and many cement plants are forced to accept limestone having higher MgO (> 3.0 %) for cement manufacture. Unsoundness problems… Read More »Raw Mix Optimisation with High MgO containing Limestone
OPC clinker samples were prepared with selected modifiers that have been reported to have significant effect on the formation of clinker phases. The role of these additives in the development and modification of the clinker… Read More »Microstructural Investigation on the role of modifiers in the stabilization of different polymorphs of Silicate phases in OPC Clinker
Usage of Fly ash based cement and concrete has become increasingly popular with the recognition that in addition to strength, other properties such as impermeability ,elastic modulus and resistance to corrosion are critical parameters for… Read More »COMPARATIVE ASSESSMENT OF POZZOLANICITY OF LOW LIME CLASS- F FLY ASHES OF VARYING AMORPHOUS CONTENT
India has an estimated total limestone reserves of 96 billion tones (March 2005 estimates) out of which nearly 30% is either low or marginal grade which is not directly usable in cement manufacture .
