Cement is a material which is used to bind other materials together. Binding means it has an effect of gluing the substances together due to cohesive and adhesive action and then hardens and sets in order to become permanent. Cement is usually not used on its own; it is mixed with other materials called aggregates to produce a …
In this process, the hydrated cement reacts with CO 2 in the air, slowly reversing some of the processes that took place in the kiln when the cement was made (this is the carbonation process; it also causes reinforcement corrosion, see Section 25.3.2). It is estimated that this may reduce the carbon footprint of the cement industry by 3–5%.
Cement Manufacturing Process Flow Chart. (i) Drying Zones: In the wet process, the drying zone is comparatively larger than the dry process. It is because the raw material in slurry form is directly fed into the kiln which has more amount of water. As shown in the figure it is the upper portion of the kiln.
4) As the materials pass through the kiln their temperature is rised upto 1300-1600 °C. The process of heating is named as "burning". The output is known as "clinker" which is 0.15-5 cm in diameter. 5) Clinker is cooled & …
Wet process. Dry Process of Manufacture of Cement: Crushing of limestone and clay in crushers and stored in silos. Grinding of crushed materials and storing in hoppers. Mixing of materials by compressed air in the right proportions to form a raw mix. Burning of raw mix in a rotary kiln to form clinkers.

Scope of concrete manufacturing LCA consists of the production systems that are to be studied, the functional unit, system boundaries, and the allocation …
Raw Materials of Cement. Most important raw materials (what is cement made of) required in the manufacture of Portland Cement are: Limestone, Clay, Gypsum, Fuel, and Water (in wet method). 1. Limestones: These are sedimentary, calcium carbonate rocks (CaC0 3 ). Most commonly they contain a small amount of magnesium carbonate also.
