Sika® ViscoCrete®-430 P is a high-performance, superplasticizer and water reducer in powder form, based on Sika® ViscoCrete® polycarboxylate (PCE) polymer technology.
Very high initial flow
Robustness regarding different sand qualities
Very good flow and self-levelling behaviour
Usage
Sika® ViscoCrete®-430 P can be used in dry mortar and binder systems with high calcium sulphate content including:
Portland and Portland composite cements
Especially cements with a high sulphate and alkali content
Alkaline activated calcium sulfate based binders, e.g. synthetic anhydrite
Sika® ViscoCrete®-430 P is especially suitable for the manufacture of calcium sulphate flow screeds (ready-mix or transport-mixing and pumping-systems) but also other self-levelling screeds and underlayments, grouts and tile adhesives.
Advantages
Sika® ViscoCrete®-430 P is adsorbed onto the surface of the binder particles and due to repulsive forces from the effect known as steric hindrance, the solid binder particles are very effectively dispersed in the mix.
The benefits of Sika® ViscoCrete®-430 P include, but are not limited to the following:
High water reduction at low dosage
Robustness regarding different sand qualities
Very high initial flow
Short mixing times due to fast adsorption
Long-term stability which enables long slump life
Efficiency over a wide pH-range
Very good flow and self-levelling behaviour
Self-compacting behaviour
Increased strength development
Improved shrinkage and creep behaviour
Compatible with other additives
Low influence on hydration, resulting in low activator/accelerator consumption
Free of formaldehyde and ammonia
