PL 5

Function: admixture that reduces mixing water and provides high uniformity of mixes. The basic additive for commercial concrete with a normal and extended consistency-retention time.

Application: ready-mix and vibro-pressed concrete, higher-class concrete (in combination with superplasticisers) and situations requiring an extended working time of the mix.

Properties: improves consistency while maintaining a constant W/C ratio, increases early and final strength, improves pumpability and workability, watertightness and frost resistance.
