Sika® Plastiment® PZ 55 R
(former MasterPozzolith® 55R)
WATER REDUCING AND RETARDING CONCRETE ADMIXTURE
Sika® Plastiment® PZ 55 R is a water based, liquid, set-retarding admixture that slows the chemical action of cement hydration, delaying the initial set in direct proportion to the dosage used. After the planned delay in initial set, hardening develops at an accelerated rate.
Suitable for use in hot and tropical climatic conditions.
Sika® Plastiment® PZ 55 R provides the following beneficial properties:
- Controlled setting times
- Increased setting time in hot weather
- Accelerated hardening after setting
- Improved workability without increased water content
- Increased strengths
- Reduced shrinkage and creep
- Long lasting control of slump loss
- Superior surface finish
- Does not contain chlorides or other steel corrosion promoting ingredients
