Review Steel slag and its applications in cement and concrete
Considering that concrete production is responsible for 8.6% of all anthropogenic CO 2 emission [28], it is clear that such a huge production is an important responsibility in terms of the environment. The concrete industry uses one billion-tons of mixing water annually [29]. In addition to mixture water, a vast amount of washing water …

Carbonation occurs gradually in concrete as CO 2 in the air reacts with cement to form water and calcium carbonate. A 2016 paper in Nature Geoscience found that since 1930, carbonation in concrete has offset 43 percent of the emissions from the chemical transformation of calcium carbonate to clinker during cement production.

Cement Production
Cement production has undergone a tremendous development from its beginnings some 2000 years ago. While the use of cement in concrete has a very long history, the industrial production of cements started in the middle of the 19th century, first with shaft kilns, which were later on replaced by rotary kilns as standard equipment worldwide.

Cement and Concrete: The Environmental Impact
The Production Process of Concrete: Concrete is constructed using cement mixed with an aggregate-- a grainy blend of materials such as stone and sand. After mixing, the concrete is poured into a mold and left to harden then use in building. The aggregates are sourced from a local body of water and crushed in a natural procedure.
