SikaPlast®-388 HN

PCE BASED SUPERPLASTICIZING AND SET RETARDING CONCRETE ADMIXTURE

SikaPlast®-388 HN is a 3rd generation polymer based high performance superplasticizer for producing soft consistency concrete.
SikaPlast®-388 HN meets the requirements of ASTM C 494 Type D & G
SikaPlast®-388 HN conforms to Type G when used at 0.8 - 1.0% dosage, depending on cement type used.

SikaPlast®-388 HN combines different modes of actions. By adsorption on the surface of the fines and keeping them apart while the hydration is in progress, SikaPlast®-388 HN effects the following concrete properties:
▪ Improve mortar phase when using coarse sand
▪ Long slump keeping and high water reduction
▪ High flowability (considerably reduced placing and compacting work)
▪ Faster evolution of early strength development
▪ Workability can be maintained up to 3 hours (still depends on admixture dosage, cement type, temperature)
▪ Improved creep and shrinkage resistance characteristics
▪ When used at higher dosages, SikaPlast®-388 HN can give extended working time
