Comparative Life Cycle Assessment of Different
Cement has long been recognized as an energy- and emission-intensive construction material. Cement production has recently experienced significant growth despite its high energy consumption, During the twentieth century, cement manufacture spread worldwide. By 2019, India and China have become the world leaders in cement production, followed by Vietnam, the United States, and Egypt. The primary cement manufacturing process involves the mining of raw materials, mainly limestone and clay, which are used in cement Cement Manufacturing—Technology, Practice, and

There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as “ clinker,” together with some 5 percent of gypsum (to control the time of set of the cement). The three processes of The processing of Portland cement clinker is the most energy-intensive phase in the cement manufacturing process, accounting for approximately all of the energy and nearly all of the fuel used. Cement production accounts for about 5% of global greenhouse gas (GHG) emissions (Kunal et al., 2012).Cement kiln dust ScienceDirect

(PDF) A Review Article on Manufacturing Process of Cement
The production process of cement involves burning of limestone and clay together in a rotary kiln at a temperature of about 1,450°C (Gaharwar, Gaurav, Singh, Singh, & Gariya, 2016). This might beDesign, technology, innovation and costs are the determining factors for the future of pyroprocessing in cement production. At the heart of the Portland Cement manufacturing process is the pyroprocessing system. This system transforms the raw mix into clinkers, which are grey, glass-hard, spherically shaped nodules that range from 0.32 Pyroprocessing: The Heart of the Matter Indian Cement

A life-cycle assessment of Portland cement manufacturing
Huntzinger et al. [15] have compared the traditional process of Portland cement manufacturing with alternative technologies and evaluated their environmental impact using LCA. The authors concludeThe cement manufacturing process involves the release of large amounts of carbon dioxide (CO2), primarily due to the calcination of limestone and the energy-intensive nature of production.Reducing carbon footprint: The journey of cement industry

Engineers from the University of Cambridge filed a patent for the world's first emissions-free route to recycle Portland cement, with an industrial-scale demonstration expected by 2024. According to the researchers, the process eliminates the emissions from kiln operation, using 80-90% less energy, and reducing total emissions by a least 50%.8.2.1 Goal and Scope of Cement and Concrete Manufacturing LCA. The goal of carrying out an LCA study of concrete is to state the prophesied use and the reasons for conducting the study.

Understanding the Manufacturing Process of Cement and its
The manufacturing of Portland cement is the most common type of cement formation which is used in the construction sector. It is a type of hydraulic cement invented by Joseph Aspdin of England in 1824. It was produced from a mixture of limestone and clay. It got its name due to its high resemblance to the Portland stone in England.The indirect approaches adopted so far are, making blended cements to reduce clinker factor (Portland pozzolana cement, Portland slag cement etc.), improving production technology (by minimizing(PDF) Use of alternative fuels in cement industry
