Sika® ViscoCrete®-1100

HIGH RANGE WATER REDUCING ADMIXTURE 

Sika® ViscoCrete®-1100 is a high range water reducing admixture with extended workability. Sika® ViscoCrete®-1100 utilizes the combination of Sika's ViscoCrete® and ViscoFlow® polycarboxylate technology with an enhanced defoaming stabilization package. Sika® ViscoCrete®-1100 meets the requirements of ASTM C494/AASHTO M 194, Type A & F.

Sika® ViscoCrete®-1100 provides the highest level of slump retention in the Sika® ViscoCrete® product line. Various levels of water reduction can be achieved by adjusting the dosage rate of Sika® ViscoCrete®-1100.     When used as a high range water reducing admixture, water reduction up to 40% can be obtained. The superplasticizing action of Sika® ViscoCrete®-1100 allows for the production of high slump/flow concrete with excellent workability and extended slump retention that can typically be placed with minimal vibration even at an extremely low water/cementitious ratio.      At lower dosages rates Sika® ViscoCrete®-1100 is an effective normal water reducing or mid-range water reducing admixture.  This application is ideal for use with lean, harsh concrete mixes or concrete containing supplementary cementitious materials.    The combined water reducing and superplasticizing action of Sika® ViscoCrete®-1100 provides the following benefits:
  
▪ Reduced water cement ratios produce more durable, dense concrete, ▪ Reduced concrete stickiness allows lower pumping pressures, ▪ Increased slump and workability improves efficiency of labor and reduces labor costs, ▪ Improved finishing characteristics, ▪ Increased strengths allow faster structural use of concrete.      Sika® ViscoCrete®-1100 does not contain intentionally added chlorides.

Usage

Sika® ViscoCrete®-1100 is designed for use in both ready mix and precast applications whenever high plasticity, extended slump retention and increased strengths are required. Sika® ViscoCrete®-1100 can be used for production of SCC (Self-Consolidating Concrete), UHPC (Ultra-High Performance Concrete) as well as for production of conventional slump concrete.

Application

Application Information

Mixing

Measure the required quantity manually or by automated dispenser. Add Sika® ViscoCrete®-1100 directly into the freshly mixed concrete, or as an integral material in the batching cycle. Do NOT mix with dry cement. Sika® ViscoCrete®-1100 may be dispensed on-site directly prior to placement. Care must be taken to mix thoroughly. When used in combination with other admixtures dispense each admixture separately into the mix.

  

Compatibility: Sika® ViscoCrete®-1100 can be used in combination with other Sika admixtures and can be successfully used in mix designs utilizing supplementary cementitious materials.
Consumption

Recommended Dosage

The typical dosage rate of Sika® ViscoCrete®-1100 will vary between 1-6 fl oz / 100 lb. (65-390 mL / 100 kg) of cement or cementitious materials. If maximum water reduction is required, dosage rates up to 12 fl oz / 100 lb. (780 mL / 100 kg) of cement or cementitious materials may be used. For UHPC (Ultra-High Performance Concrete) applications higher dosage rates may be required. Various factors will affect the dosage rates. 

  

Trial mixes with the actual materials should be conducted to determine the required dosage for optimum performance.

   

To the extent specialized materials are used, extreme ambient temperatures are encountered, or for other unusual project conditions, dosage rates outside the typical range may be required. For dosage rates outside the typical range, please contact your local Sika representative or the Sika Technical Services Department at 1-800-933-7452.
