Sika® ViscoCrete®-225 P

Sika® ViscoCrete®-225 Powder may be used in a variety of concrete applications but is especially suited for the production of mortar and concrete dry mix. High water reduction, excellent flowability, coupled with good early strengths, have a very positive influence on the properties of the mortars and concrete containing it.

Sika® ViscoCrete®-225 Powder facilitates extreme water reduction, excellent flowability, optimal cohesion, and promotes excellent self-compacting behavior. Sika® ViscoCrete®-225 Powder is recommended for the following applications:

• Grouts in general (including non-shrink grouts)
• Screeds in general (including self-levelling screeds)
• Gypsum and anhydrite screeds

Sika® ViscoCrete®-225 Powder has been formulated to provide maximum water reduction however is suitable and may be utilized for all levels of water reduction.

Can be combined with other Sika® ViscoCrete® powders to attain maximum effects such as flowability and retardation.

Sika® ViscoCrete®-225 Powder is a unique, specially formulated polycarboxylate powder that combines different mechanisms and is compatible with a variety of cement chemistries. Through surface adsorption and steric separation effect on the binder particles, in parallel to the hydration process, the following advantages may be observed:

• Effective when utilized with cements that have high C3A, sulphate and alkali content.
• Effective when utilized with ordinary portland cements (OPC) and blends of OPC and aluminate cements.
• Compatible with other additives (i.e. citric acid).
• Extremely high water reduction (resulting in high density and strengths).
• Excellent flowability.
• Increased high early strength development.
• Improved shrinkage and creep behavior.
• Low absorption time.
• Medium retardation.
• Ideal for use in self-levelling, self-compacting applications.
