High Range Water Reducing Admixture
Sika® ViscoCrete®-2110 is a high range water reducer and superplasticizer utilizing Sika’s ViscoCrete® polycarboxylate polymer technology. Sika® Sika® ViscoCrete®-2110 meets the requirements for ASTMC-494 Types A and F and AASHTO M-194 Types A and F admixture.
Sika® ViscoCrete®-2110 can be used for all levels of water reduction in various types of concrete ranging from dry cast applications, conventional concrete to SCC (Self Consolidating Concrete). Sika® ViscoCrete®-2110 will deliver water reduction up to 45 %. The special formulation of Sika® ViscoCrete®-2110 increases compressive strength of concrete and helps maintain the plasticity of the concrete over prolonged period of time. Sika® ViscoCrete®-2110 extends concrete workability time during warmer months when slump loss and fast stiffening of the fresh concrete can be a concern. The superplasticizing action of Sika® ViscoCrete®-2110 provides high slump / flowing concrete that be placed with minimal or no vibration even at very low water cementitious ratios, as low as 0.25.
Sika® ViscoCrete®-2110 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®-2110 is suitable for all levels of water reduction.
The superplasticizing action of Sika® ViscoCrete®-2110 provides high slump, flowing concrete that maintains excellent workability and may be placed with minimal vibration even at very low water cementitious ratio’s as low as 0.25. Sika® ViscoCrete®-2110 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®-2110 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®-2110 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®-2110 has been formulated to provide maximum water reduction and extended slump retention throughout entire dosage range.
- Extended slump life.
- Increased compressive strength when compared to reference concrete with same w/cm ratio.
- High early compressive strengths for earlier removal of forms and structural use of concrete.
- High ultimate strengths allow for greater engineering design flexibility and structural economies.
- Reduced water cementitious ratios produce more durable, dense concrete with reduced permeability.
- Highly effective plasticizer reduces surface defects in concrete elements and improves aesthetic appearance.
- Ideal for the production of Self Consolidating Concrete.
