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 . The… Read More »Maximized use of low grade Limestone in Dry process of Cement manufacture through use of conventional froth floatation with innovative process adoption

Abstract : The use of fly ash as supplementary cementitious material was originally motivated by its consistent pozzolanic activity and provide for sustainable development in the cement industry. India has been a pioneer in the… Read More »EFFECT OF CHEMICO-MINERALOGICAL CHARACTERISTICS OF INDIAN FLY ASHES ON PROPERTIES OF BLENDED CEMENT CONCRETE
