Sika® Plastiment®-40 KE
Water reducing admixture for concrete
Sika® Plastiment® 40 KE is a plasticiser for concrete and mortar based on modified PCE/Gluconates
Sika® Plastiment® 40 KE is a powerful plasticiser which acts through several different mechanisms including surface adsorption separating the cementitious binder particles due to the electrokinetic potential. The following advantageous properties are achieved:
- Superior plasticising effect, resulting in improved flow, placing and compaction characteristics
- Keeps extended workability time with many difficult cements despite water reduction
- Water reduction, resulting in improved density, higher strength and reduced permeability
- Reduced tendency to shrinkage and creep ▪ Reduced carbonation of the concrete
- Improved cohesion of the concrete
