ProLong® L (Hydration Stabilizer) is a ready-to-use liquid solution manufactured to control the hydration process in Portland cement concretes and concrete wash water. This advanced hydration modifier coats the hydrating cement particles in the concrete and wash water, resulting in the delay of the hydration chemical reaction.

ProLong© L (Hydration Stabilizer) provides a means to control concrete plasticity, slump, temperature, and postpones the set of the concrete for a predictable period of time. Eventually, the ProLong L dosage is chemically consumed and normal hydration continues.
