- Volume discount
A polyoxyalkylene surfactant shrinkage-reducer that lowers capillary tension, markedly reducing plastic and drying shrinkage, lowering crack risk and improving impermeability and stability.
Lower drying shrinkage · Crack control · Better impermeability
- Form
- Liquid
- Recommended dosage
- 1.0% – 2.0% by binder weight
Overview
This shrinkage-reducer is a polyoxyalkylene surfactant that lowers the meniscus tension in capillary pores, reducing plastic and drying shrinkage caused by water evaporation and migration, and cutting cracking at the source.
Key benefits
- Significantly lowers drying shrinkage, fewer surface/structural cracks
- Improves impermeability and dimensional stability
- Compatible blended with PCE superplasticizers
- Suited to large slabs and thin-wall elements
Usage
Add with the superplasticizer; adjust to target shrinkage control. It mainly improves shrinkage cracking and does not replace structural crack-control measures; pair large pours with proper joints and curing.
Typical use
Mass/slab structures, impermeable structures, repair mortar and flooring.
