Usage

Sika® ViscoCrete®-125 P is formulated for use in dry mortar applications and can be used with different hydraulic binder systems according to the performance required, including:
  • Portland cement (OPC) and cement blends
  • Ternary blended binders
  • Calcium sulphate (gypsum) based binders
Sika® ViscoCrete®-125 P is especially suitable for the following dry-mortar applications:
  • Cement and anhydrite screeds (including self-levelling screeds) and underlayments
  • Grouts (including non-shrink grouts) & tile adhesives based on Portland cement (OPC).
 

Advantages

Sika® ViscoCrete® is adsorbed onto the surface of the binder particies and due to repulsive forces from the effect known as steric hindrance, the solid binder particiers are very effectively dispersed in the mix. Thecharateristics and advantages of Sika® ViscoCrete®-125 P include:
  • High water reduction at low dosage (resulting in shorter drying times, higher densities and strengths)
  • Very good flow and self-levelling behaviour
  • Reduced mixing times due to fast adsorption
  • Long-term stability which enables long slump life
  • Increased strength development
  • Improved shrinkage and creep behaviour
  • Efficiency over a wide pH-range
  • Compatible with other additives
  • Low influence on hydration, thus low activator/accelerator consumption
  • Free of formaldehyde and ammonia

Application Information

Compatibility

Sika® ViscoCrete®-125 P may be combined with many other Sika products as well as with most existing accelerators, retarders and other additives used in dry-mortar applications. In these combinations with Sika® ViscoCrete®-125 P, additional improvements in flow and retardation of the mortar can also be achieved.
Important: Always conduct trials before combining products in any specific mix design and contact our Technical Services Department for any additional information and advice concerning specific combinations with other products.

Dispensing

Sika® ViscoCrete®-125 P is added to the dry mix. For optimum utilisation of the high water reduction capability, a minimum wet mixing time of 30 seconds is recommended for the mortar before use.
Consumption

Recommended Dosage

Depending on application the dosage rate of Sika® ViscoCrete®-125 P is between 0.05 - 0.5 % by weight of binder. At high dosage and at low temperatures Sika® ViscoCrete®-125 P can also cause retardation.
