The decarbonation of limestone to give the calcium required to form silicates and aluminates in clinker releases roughly 0.53 t CO 2 per ton of clinker [8]. In 2005, cement production (total cementitious sales including ordinary Portland cement (OPC) and OPC blends) had an average emission intensity of 0.89 with a range of 0.65–0.92 t CO 2
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 resulting material is known as clinker, which is ground down and mixed with chalk, becoming cement. Between calcination and energy use, the production of one metric ton of cement results in the approximate emission of 1 metric ton of CO2 into the atmosphere. The addition of sand and gravel (known as aggregates) to cement produces
Another way to decarbonize clinker is to capture the CO2 emitted by its production, use it and/or store it safely in an inert form forever. This process — known as carbon capture, use and storage — is nascent, expensive and can be energyintensive. That’s especially true if the flue gases captured during clinker production contains low
The consumption of coal in dry process system ranges from 2025% of clinker production. That means 0.200.25 t of coal is consumed to produce one tonne of clinker. The cement industry consumes

90 million tons, and masonry cement production continued to remain steady at 2.4 million tons. Cement was produced at 96 plants in 34 States, and at 2 plants in Puerto Rico. Texas, Missouri, California, and Florida were, in descending order of production, the four leading cementproducing States and accounted for nearly 44% of
Cement manufacturing is highly energy and emissionsintensive because of the extreme heat required to produce it. Producing a ton of cement requires 4.7 million BTU of energy, equivalent to about 400 pounds of coal, and generates nearly a ton of CO 2. Given its high emissions and critical importance to society, cement is an obvious place to

operating above the 50th percentile (i.e., those plants with intensities lower than 0.838 CO2 per ton of clinker or 0.776 CO2 per ton of cement) are operating at above average carbon performance and emit lower levels of CO2 per ton of clinker or cement than plants below the median. Plants operating at or below the 25th percentile emit
In June , the cement clinker price per ton stood at $76 (CIF, US) in June , falling by 6.7% against the previous month. Overall, the import price showed a perceptible descent. The growth pace was the most rapid in May an increase of 42% against the previous month. The import price peaked at $94 per ton in February ;
produce one kilogram of the clinker, which is equivalent to 1.55 kg of the raw mix. This can also be calculated that for one kilogram of raw meal, 49.27g of coal is required. But the observed heat required in cement kiln is 850 kcal/kg, which is almost double to that 420 kcal/kg. So the use of coal becomes up to
