Water Reduction: Sika® ViscoCrete®-2100 can be dosed in small amounts to obtain water reduction from 10−15 % and will achieve water reduction up to 45 % at high dosage rates. Sika® ViscoCrete®-2100 is suitable for all levels of water reduction. High Plasticity: The superplasticizing action of Sika® ViscoCrete®-2100 provides high-slump, flowing concrete that maintains excellent workability and may be placed with minimal vibration even at very low water cement ratio’s as low as 0.25.
Sika® ViscoCrete®-2100 plasticized concrete is highly fluid while maintaining complete cohesion within the concrete matrix to eliminate excessive bleeding or segregation.  
Extended Slump Life and Set Control: Sika® ViscoCrete®-2100 has been formulated to provide controlled and predictable extended slump life for periods of 60 to 90 minutes with normal set times.  
The combined high range water reduction and superplasticizing action of Sika® ViscoCrete®-2100 provide the following benefits in hardened concrete:   

• Higher ultimate strengths allow for greater engineering design flexibility and structural economies
• Reduced water cement ratios produce more durable, dense concrete with reduced permeability
• Highly effective plasticizer reduces surface defects in concrete elements and improves aesthetic appearance

  
Sika® ViscoCrete®-2100 has been formulated to provide maximum water reduction and extended slump retention at low dosages.

Sika® ViscoCrete®-225 P 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 (resulting in greatly reduced placing and compacting efforts).
• Increased high early strength development.
• Improved shrinkage and creep behavior.
• Low absorption time, “wets out” faster then competitive materials.
• Medium retardation.
• Ideal for use in self-leveling, self-compacting applications.
