Cement testing as per Indian standards IS: 4031, i.e., primarily determination of Normal Consistency of cements and subsequently gauging of cement mortar is carried out manually and requires skill and experience for better accuracy, precision… Read More »MANUAL V/S MECHANICAL MIXING: ITS IMPACT ON CEMENT STRENGTHS
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 manufacture of… Read More »EFFECT OF CHEMICO-MINERALOGICAL CHARACTERISTICS OF INDIAN FLY ASHES ON THE PROPERTIES BLENDED CEMENT CONCRETE
Air cooled steel slag (ACSS) generated During Steel manufacturing process is very hard & difficult to grind in nature & is highly crystalline in nature & so cannot be used as MIC in Slag cement… Read More » Assessment of use of Air cooled Steel Slag /Granulated Blast Furnace Slag as Corrective in Cement Raw Mix
In cement manufacture, for the selection, design and operations of the pyroprocessing system, it is essential to know the energy requirement in clinkerisation of cement raw mix. This heat of reaction is a measure of … Read More »DIFFERENTIAL THERMAL ANALYSIS – – A TOOL FOR ASSESSMENT OF THE HEAT OF REACTION IN CLINKERISATION OF CEMENT RAW MIXES
Nearly 73% of India’s total installed power generation capacity is thermal, of which coal-based generation is 90%. Presently 90 million tonnes of fly ash is being generated annually in India, with 65 000 acres of… Read More »Future Technological options for Increased Fly ash utilisation– A Review
