Sika® ViscoCrete®-6100
HIGH RANGE WATER REDUCING ADMIXTURE
Sika® ViscoCrete®-6100 is a high range water reducing and superplasticizing admixture utilizing Sika’s ViscoCrete® polycarboxylate polymer technology.
- Higher early compressive strengths for earlier removal of forms and structural use of 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
- Ideal for the production of Self-Consolidating Concrete (SCC)
- Ideal for ready-mix trucks
- Formulated to provide maximum water reduction, increased early strength, improved finishing characteristics, especially when a broom is desired
- Sika® ViscoCrete®-6100 does not contain formaldehyde, calcium chloride or any other intentionally added chlorides, and will not initiate or promote the corrosion of steel present in the concrete
Usage
- Sika® ViscoCrete®-6100 is designed for conventional precast/prestress applications, and may also be used for the production of Self-Consolidating Concrete (SCC).
- Sika® ViscoCrete®-6100 is a high range water reducer that provides excellent plasticity, and may be combined with accelerator or retarder admixture to control the set time and slump life.
Advantages
Water Reduction: Sika® ViscoCrete®-6100 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®-6100 is suitable for all levels of water reduction. High Plasticity and Cohesion: The superplasticizing action of Sika® ViscoCrete®-6100 provides high-slump, flowing concrete that maintains excellent workability, and may be placed with minimal or no vibration even at very low water cement ratios as low as 0.25. Sika® ViscoCrete®-6100 maintains excellent cohesion within the concrete matrix, and eliminates excessive bleeding or segregation. The unique plasticizing effect of Sika® ViscoCrete®-6100 provides excellent formed surface finish. The combined high range water reduction and superplasticizing action of Sika® ViscoCrete®-6100 provide the following benefits in hardened concrete:- Higher early compressive strengths for earlier removal of forms and structural use of 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
- Ideal for the production of Self-Consolidating Concrete (SCC)
- Ideal for ready-mix trucks
- Formulated to provide maximum water reduction, increased early strength, improved finishing characteristics, especially when a broom is desired
- Sika® ViscoCrete®-6100 does not contain formaldehyde, calcium chloride or any other intentionally added chlorides, and will not initiate or promote the corrosion of steel present in the concrete

Application
Mixing
For best superplasticizing results, add Sika® ViscoCrete®-6100 directly to freshly mixed concrete in the concrete mixer at the end of the batching cycle.
Sika® ViscoCrete®-6100 may also be dispensed as an integral material during the regular admixture batching cycle, or into freshly mixed concrete in a ready-mix truck, at the concrete plant. To optimize the superplasticizing effect after the addition of Sika® ViscoCrete®-6100, Sika recommends that the combined materials be mixed for 60−80 revolutions either in the concrete mixer or in the ready-mix truck.
Do not introduce Sika® ViscoCrete®-6100 directly onto dry cementitious materials.
Combination with other admixtures: Sika® ViscoCrete®-6100 is highly effective as a single admixture or in combination with other admixtures in the Sika system. If used in combination with certain Sikament® high range water reducers it may affect the plastic properties of fresh concrete. Contact a Sika Canada Technical Sales Representative for further information.
Combination with Microsilica: Sika® ViscoCrete®-6100 is particularly well suited for use with microsilica because of its water reduction capability.
Recommended Dosage
Dosage rates will vary according to materials used, ambient conditions and the requirements of a specific project. Sika recommends dosage at 195–520 mL/100 kg (3–8 fl.oz. per 100 lb) of cementitious for general concrete applications. If maximum water reduction is required dosage up to 780 mL/100 kg (12 fl.oz./100 lb) of cementitious may be used.
Dosage rates outside the recommended range may be used where specialized materials such as microsilica are specified, extreme ambient conditions are encountered or unusual project conditions require special consideration. In this case, please contact your Sika Canada Technical Sales Representative for more information and assistance.
