Moisture Mitigation in Slabs Concrete Moisture. Concrete with a high water-cement ratio produces more capillaries, making it easier for moisture to move through a slab quickly, but more water must leave, which also takes time. Slab drying time is dependent on the water-cement ratio and the resulting capillary structure. Self-desiccation.

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.
