USES
Sika® ViscoCrete®-540 P is formulated for applications in systems with high calcium sulfate content or pure gypsum binders. The product is especially suitable for the production of dry-mixed mortars and concrete for applications like:
▪ Floor screeds, self-leveling screeds and underlayments
▪ Grouts, non-shrink grouts, repair mortars, tile adhesives
▪ Building plaster, render, stucco, bonding/filling compound, molding plaster,dental & medical plaster
▪ Gypsum-based self-leveling mortar
▪ Cement-based self-leveling mortar
High water reduction and excellent flowability have a positive influence on the above mentioned applications.
Sika® ViscoCrete®-540 P can be used in the following binder systems:
▪ Calcium sulfate binders (α- and β-hemihydrate,natural/thermal/syntheticanhydrite)
▪ Ternary compounds (Portland cement + calcium aluminate cement +calcium sulfate)
▪ Portland cement and cement blends, especially cement with high C3A,sulfate and alkali content
CHARACTERISTICS / ADVANTAGES
The benefits of Sika® ViscoCrete®-540 P include:
▪ High water reduction (resulting in high density and strength)
▪ Excellent flowability (resulting in highly reduced placing- and compacting efforts)
▪ Increased early strength development
▪ Improved shrinkage and creep behavior
▪ Reduced mixing times due to rapid adsorption
▪ Long-term stability enables long slump life
▪ Low influence on hydration
▪ Efficiency over a wide pH-range
▪ Compatible with other additives, e.g. citric acid
▪ Free of formaldehyde (unlike SNF/SMF) and ammonia
