Production of cement refers to the method of energy and resource used, which absorbs almost 12% to 15% of total industrial energy utilization [28]. It also actually reported for 5% to 8% of CO 2 emissions from cement production [26]. Global cement manufacturing hit 4.1 Gt amount of CO 2 during 2017 [30].

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 cement-producing States and accounted for nearly 44% of U.S. production.
Though the first Indian cement factory was setup in Porbandar Gujarat in 1904, yet the credit goes to South Indian industries Ltd. Madras now Chennai for pioneering the production of Cement in India in the same year. Between the year 1912 to 1913 three cement factories were setup in Porbandar Gujarat, Katni Madhya Pradesh and Bundi …
2017, equivalent to a reduction in cement per capita from 0.5 to 0.3 tonnes per person (3). The CO 2 intensity of cement production over that period has improved by about 7% (0.6t of CO 2 emitted per tonne of cement in 2017) (2). By 2050, cement production in the EU is expected to remain below pre-2010 levels, ranging between 165Mt

cement production process by up to 40%. The developers also assert that LC3 is cost-effective and would require minimal capital investments at existing cement mills. Potential technical challenges to decarbonizing cement and concrete production remain. For cement that incorporates a higher share of SCMs and alternative binding materials,
Properties of cement : Setting and hardening When the cement is mixed with water, hydration and hydrolysis reactions of Bogue compounds of cement begin, resulting in formation of gel and crystalline products. These products have the ability to surround inert materials liks sand, bricks, crushed stones,etc.
