The cement industry is an energy intensive industry consuming about 4 GJ per tonne of cement produced. A thermodynamic analysis for cogeneration using the waste heat streams is not easily available. Data from a working 1 Mt per annum plant in India is used to obtain an energy balance for the system and a Sankey diagram is drawn.

2002-4-1 The cement industry is an energy intensive industry. In India the industry accounts for 10.3% of total fuel consumption in the manufacturing sector . The energy costs account for about 26% of the manufacturing cost of cement . In terms of the primary energy usage about 25% of the input energy is electricity while 75% is thermal energy . The specific energy consumption varies from about 3.40 GJ/t

1998-8-26 materials-flow analysis is the commodity mass balance study, which follows and quantifies the flow of a single commodity through its entire cycle. These analyses identify areas where adverse impacts could be minimized through reducing wastes at the source of the materials, improving waste utilization, and enhancing efficiencies.

2019-4-30 Abstract The cement industry contributes about 5% to global anthropogenic CO2 emissions, making the cement industry an important sector for CO2-emission mitigation strategies. CO2 is emitted from the calcination process of limestone, from combustion of fuels in the kiln, as well as from power generation. In this paper, we review the total CO2 emissions from cement making, including process

2020-8-18 For ordinary cement stone, the initial Young’s modulus is 8.37 GPa, and the unloading Young’s modulus after the 20th cycle is 6.12 GPa, which decreased by 26.8%. However, for low residual strain cement stone, the initial Young’s modulus is 5.49 GPa, and the unloading Young’s modulus after the 20th cycle is 4.95 GPa, which decreased by 9.8%.

2020-10-13 Portland Cement manufacture usually requires about 100kWh of electrical energy per tonne of product. Almost half of this is used in the fine grinding of clinker (and other components) to make the cement. Some supplementary cementitious materials (e.g. granulated slags) require even more energy for fine grinding than PC clinker.
