formula for maximum size in cement mill
CEMENT CONCRETE MIX DESIGN . 2015 9 15 4 Maximum nominal size of aggregate In general larger the maximum size of aggregate smaller is the cement requirement for a particular water cement ratio because the workability of concrete increases with increase in maximum size of the aggregate However the compressive strength tends to increase with the decrease in size of aggregate.

Grinding aids for high performance cements
Grinding aids are organic compounds that are added to the mill during cement grinding. Their main purpose is to reduce the energy required to grind the clinker into a given fineness. In addition, some products (usually referred to as performance enhancers) provide positive effect on cement hydration improving strength development [1].

CEMENT RAW MATERIALS - International Cement Review
Cement clinker and finished cement are traded internationally. Cement manufacture is a very energy intensive process and results in the production of large amounts of carbon dioxide (CO 2). The carbon dioxide is chiefly produced when the calcareous raw material is calcined to produce calcium oxide. Generally around 0.5 tonnes
