aggregate. This is achieved through cement colour and/or the addition of pigments (oxides). Since the course aggregate contributes significantly to the surface colour, oxide dosage rates of only 1–2% by mass of cement are typical, compared with 3–8% for ordinary coloured concrete (ie concrete in which the coarse aggregate is not to be exposed).

Handbook for the surface treatment of concrete

Grinding is the most widely used method of removing laitance layers and other impurities. Standard PSK 2703 differentiates between two classes of grinding: surface and in-depth grinding. The process of surface grinding removes all fine laitance and other traces of weak surface layers from the entire floor area, revealing the fine-grained aggregate.

CEMENT RAW MATERIALS - International Cement Review

and alumina. Finished cement is produced by finely grinding together around 95% cement clinker with 5% gypsum (or anhydrite) which helps to retard the setting time of the cement. The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone.

1 Lab Manual of Concrete Technology

The fineness of cement has an important bearing on the rate of hydration and hence on the rate of gain of strength and also on the rate of evolution of heat. Finer cement offers a greater surface area for hydration and hence faster the development of strength, (Fig. 3). The fineness of grinding has increased over the years.
