Sika® ViscoCrete®-190 SC

Sika® ViscoCrete®-190 SC is designed for high quality shotcrete and may also be used for the production of  high performance concrete and Self Compacting Concrete (SCC). Sika® ViscoCrete®-190 SC is a high range water reducer that provides excellent plasticity and  slump life. It is fully compatible with the entire range of Sika® Sigunit . Sika® ViscoCrete®-190 SC can be combined with accelerating or retarding admixtures to achieve required compressive strength and setting time.

Advantages

Water Reduction: Sika® ViscoCrete®-190 SC can be dosed in small amounts to obtain water reduction from 10–15 %, and will achieve water reduction up to more than 30 % at high dosage rates.   High Plasticity and neutral set. The superplasticizing action of Sika® ViscoCrete®-190 SC provides high slump, flowing concrete that maintains excellent workability with minimal set delay. The high range water reduction of Sika® ViscoCrete®-190 SC provides the following benefits in  concrete:

• Ideal for the production of wet shotcrete.
• High early compressive strength for earlier removal of forms and structural use of concrete.
• High ultimate strength allow for greater engineering design flexibility and structural economies.
• Reduced water cement ratios produce more durable, denser concrete with reduced permeability.
• Sika® ViscoCrete®-190 SC has been formulated to provide maximum water reduction, increased early strength, improved durability.

Dispensing

Dry batching plant.

Dose Sika® ViscoCrete®-190 SC with 80% of the mixing water then load all the remaining components, mix thoroughly for a minimum time of 60 seconds per cubic meter. Add the remaining 20% of batching water then.

Wet batching plant

Sika® ViscoCrete®-190 SC may also be dispensed as an integral material during the regular admixture batching cycle of the concrete mixer.

Do not add it to a dry mix

Consumption

 

Recommended Dosage

Dosage rates will vary according to materials used, ambient conditions and the requirements of a specific project. Sika recommends dosage at 300–1000 ml/100 kg  of cementitious for general concrete applications. If maximum water reduction is required, dosage up 1500 ml/100 kg  of cementitious may be used. In Shotcrete the typical dosage ranges between 750 ml and 1500 ml/100kg of cementitious materials.

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. Please contact your Sika representative for more information and assistance.
