Production of cement and its environmental impact

It is estimated that global cement production reached 4.1 giga-tons in 2019, with China producing the large share. Because of the importance of cement as a construction material as well as the abundant availability of raw materials (limestone + clay), cement is produced in almost all the countries in the world.

RAW MATERIALS IN CEMENT PRODUCTION energosteel

The main materials used in cement production are minerals containing calcium oxide, silex, alumina and iron oxide. These components are rarely found in one type of raw material; therefore, for the cement production the raw mix is selected for the following components: CARBONATE COMPONENT (rich in calx) is contained in the raw mix in a The production of a ton of Portland cement requires 1.50 t of raw materials (Elchalakani et al., 2014). This means that approximately 5.40 Bt of raw materials were consumed globally for cement production in 2011, whereas the ratio of the amount of raw materials to per ton of clinker is usually 1.50 t–1.69 t in China, according to cementAnalysis of material flow and consumption in cement production process

Health Risk and Environmental Assessment of Cement Production

The cement manufacturing industry has played a fundamental role in global economic development, but its production is a major facilitator to anthropogenic CO2 release and solid waste generation. Nigeria has the largest cement industry in West Africa, with an aggregate capacity of 58.9 million metric tonnes (MMT) per year. The Ministry for The cement industry is facing numerous challenges in the 21st century due to depleting natural fuel resources, shortage of raw materials, exponentially increasing cement demand and climate linked environmental concerns.

A decision support tool for cement industry to select energy

Beside technological improvements, the composition of raw materials and the final product may also influence energy consumption. As shown in Fig. 1 after the crushing process, pre-blending and grinding, the raw materials are calcined to produce the semi-final product called clinker. The calcination process uses approximately 24% of the While total electrical energy consumption for cement production is about 100 kWh/ton of cement, roughly two thirds are used for particle size reduction [2]. About 65% of the total electrical energy used in a cement plant is utilized for the grinding of coal, raw materials and clinker Fig. 1.

Energy and thermodynamic analysis of a typical cement production

1. Introduction. Cement production is one of the energy-intensive industries, which consumes nearly 5% of the global industrial energy [1, 2].In cement production, energy cost accounts for 30%–40% of the total production cost [3].In particular, China's cement production accounts for 55–60% of the world's cement production As a common building material, cement is widely used in housing and road construction. In general, the global cement industry accounts for about 5–7% of the world’s CO 2 emissions 1.Since 1990China’s provincial process CO2 emissions from cement production
