Term: Curing
Definition: The process of maintaining adequate moisture, temperature, and time to allow the concrete to achieve its desired strength and durability.
Term: Plastic Shrinkage Cracks
Definition: Cracks that may occur in fresh concrete due to rapid drying, especially in mixes with low water-to-cement ratios.
Term: Evaporation Reducers
Definition: Chemicals applied to the surface of fresh concrete to reduce water evaporation, thereby minimizing drying and potential cracking.
Term: Initial Curing
Definition: Methods employed to prevent moisture loss from concrete before the final set using techniques like fogging and covering.
Term: Final Curing
Definition: The application of water or curing compounds to hardened concrete to maintain moisture content and promote hydration.
