Mathematics
ScanSolve AI Answer
Answer
Admixtures are substances added to concrete other than cement, water, and aggregates to modify its properties. They can improve workability, accelerate or retard setting, increase strength, or enhance durability.
Retarders are a specific type of admixture that slows down the rate of cement hydration. This delays the setting time of the concrete, which is useful in hot weather or when long-distance transportation is required.
