1. Introduction. Nowadays, cement manufacturing is an energy-intensive industry. The energy costs of cement industry are about 40% of the product cost that indicates that this sector is one of the biggest CO 2 emitter. The global anthropogenic CO 2 emission of cement industry is approximately 5% [].The International Energy Agency …
The cement manufacturing process starts from the mining of raw materials that are used in cement manufacturing, mainly limestone and clays. A limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km. ... The cement industry is a natural producer of CO2: 60% of emissions are due to the ...
Electrical energy only comprises between 10 and 15% of the overall energy demand for cement production but is a notable cost driver [4], [5].Over the last decades the average specific electrical energy consumption has decreased (Fig. 3) [6].However, there are counteracting effects: CO 2-emissions can be significantly reduced by the …

Slag use in cement manufacture and cementitious applications. George C. Wang, in The Utilization of Slag in Civil Infrastructure Construction, 2016 13.2.2.2 Energy use in cement production. The production of cement is an energy-intensive process using primarily fossil fuel sources.
Cement production is one of the most energy-intensive and highest carbon dioxide (CO2) emitting manufacturing processes. In fact, the cement industry alone accounts for around 7% of total anthropogenic CO2 emissions in the world. Mexico is the 11th largest cement producing country in the world producing 51 million tonne (Mt) of cement in 2021.
CDIAC's method for estimating process emissions from cement production by country is taken from a report by Griffin (1987) and requires that cement production data in tonnes are multiplied by a fixed factor …
Below, this paper analyzes and identifies some of the determinants that explain cement industry production in Mexico. The objective of this study was to identify the effect of …
Fossil fuel combustion to meet heating needs accounts for 35% of cements CO2 emissions. The remaining 65% are due to direct process emissions, which must also be addressed. By 2050, cement production in …

Cement production is an energy-intensive process consuming thermal energy of the order of 3.3 GJ/tonne of clinker produced, which accounts for 30 – 40 percent of production costs (Giddings et al., 2000; EC, 2001). Worldwide, coal is the predominant fuel burned in cement kilns.
The production of 1 ton of cement, when accounting for the entire process, corresponds to a release of 0,66 – 0,8 ton of CO 2 (IEA, 2009). For cement production, there are two aspects that result in CO 2 emissions: industrial process emissions and energy emissions.

Five concrete mixes were produced with a water/cement ratio (w/c) of 0.5 and other five mixes with a w/c of 0.7. Five replacement rates of coarse aggregate by recycled coarse aggregate (%R) were used: 0, 25, 50, 75, and . OPC was used in all mixtures, and its production process was considered independently from the rest of the materials.
The use of alternatives to fossil fuels has been growing rapidly in cement production in recent decades.
