Cement Kilns: Size Reduction and Grinding

Cement specifications clearly needed a way of prescribing the fineness of cement, and the sieve method was written into standards in the absence of any more useful measure, despite the fact that it provided little guidance as to the likely quality of the cement, particularly as the number of different grinding technologies multiplied.

Concrete - Wikipedia

Concrete, usually Portland cement concrete, is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens over time—most frequently a lime-based cement binder, such as Portland cement, but sometimes with other hydraulic cements, such as a calcium aluminate cement.

Cement Content - GBG

Cement Content Testing. The cement content of concrete is important from the aspect of durability, impermeability and strength. Too low a cement content may cause inadequate structural capability or more frequently may not provide a durable protective environment for the steel reinforcement, permitting rapid carbonation and subsequent loss of the protective alkaline environment for the steel.
