TL;DR
An admixture is a chemical or mineral ingredient added to concrete during batching to change how it behaves, beyond the basic cement, water, and aggregate. Common types include air entrainers for freeze-thaw durability, water reducers and superplasticizers for strength and workability, accelerators for cold-weather pours, and retarders for hot ones.

Most are governed by ASTM C494 and dosed at the ready-mix plant per the mix design. The delivery ticket lists what went into the load, which is how an inspector verifies the specified mix.
