Compaction is the process in which the air bubbles are eliminated from the freshly placed concrete. It is required to increase the ultimate strength of concrete by enhancing the bond with reinforcement. Curing: Curing is the process in which the concrete keeps its moisture for a certain time period to complete the hydration process.

Modern dry-process cement plants with an efficient grinding and pyro processing system, typically consume less than 700 kcal/kg-cl of thermal energy and 100 kWh/mt of electrical energy. Older plants with inefficient systems, combined with operational and maintenance failure, tend to have much higher energy consumption.

For the latter, in comparison to the clinkerization process of Portland cement where 1450 °C is normally required, the operation temperature can be reduced to 1250 °C for CSA cement [19]. Such a temperature difference would also contribute to a reduction of up to 0.04 tons of CO 2 per ton of CSA cement production.
