Grinders take more time to use effectively than shotblasters. The tooling or diamonds for grinding are more expensive which makes grinding a more expensive procedure than shot blasting. On the other hand, grinders produce a smoother finish that is ideal for interior spaces. Ground concrete can accept a lighter finish or remain unfinished.

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

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.
