Sika® ViscoCrete®-1000
HIGH RANGE WATER REDUCING ADMIXTURE
Sika® ViscoCrete®-1000 is a high range water-reducer utilizing the combination of Sika® ViscoCrete® and Sika® ViscoFlow® Technology. Its unique formulation is based on polycarboxylate technology.
High-Range Water Reducing Applications: When used as a high range water reducing admixture, water reduction up to 35 % can be obtained. The superplasticizing action allows for the production of high slump flowing concrete with excellent workability and extended slump retention that can be placed with minimum vibration even at a low water/cement ratio. The dispersing action of Sika® ViscoCrete®-1000 maximizes cement hydration efficiency and improves concrete’s early and long term compressive strengths. Extended slump retention does not have negative effect on setting times. Mid-Range Water Reducing Applications: At a lower dosage, Sika® ViscoCrete®-1000 can be used as a cost effective mid range water reducing admixture or simply as a water reducing admixture for production of conventional slump concrete. When used as a mid range water reducing admixture, water reduction up to 15 % can be obtained. This application is ideal for use with lean, harsh concrete mixes or concrete containing flyash. Sika® ViscoCrete®-1000 will improve workability and finishability.
The combined water reducing and superplasticizing action provide the following benefits:
- Higher early and ultimate strengths for cost effective high strength concrete and earlier structural use of concrete.
- Higher early strengths allow faster demolding and more efficient use of forms to precast producers.
- Improved slump retention will extend workability without negative effect on setting time characteristics of the concrete mixture.
- Increased slump improves workability and reduces labor costs.
- Greater concrete density reduces permeability and increases durability.
Sika® ViscoCrete®-1000 does not contain calcium chloride or any other intentionally added chlorides and will not initiate or contribute to corrosion on steel reinforcement present in the concrete.
Usage
- Sika® ViscoCrete®-1000 is recommended for production of all high strength, concrete products, whenever high plasticity, prolonged slump retention and increased early/ultimate strengths are required.
- Sika® ViscoCrete®-1000 can be used for production of SCC (Self-Consolidating Concrete) as well as for production of conventional slump concrete.
Advantages
The implementation of the latest Sika® ViscoFlow® Technology allows Sika® ViscoCrete®-1000 to extend the slump retention without a negative impact on set time. This is beneficial especially in a hot climate environment when the slump loss of a concrete mixture is more likely to occur. Sika® ViscoCrete®-1000 can be used for the production of SCC as well as for the production of conventional slump concrete.High-Range Water Reducing Applications: When used as a high range water reducing admixture, water reduction up to 35 % can be obtained.

Specific Advice
Curing
Proper curing according to CSA A23.1 guidelines should be always followed to achieve maximum possible quality of concrete.
Application
Mixing
Measure the required quantity manually or by automated dispenser. Add Sika® ViscoCrete®-1000 directly into the freshly mixed concrete, or as an integral material in the batching cycle. Do not mix with dry cement. Sika® ViscoCrete®-1000 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. Sika recommends that the combined materials be mixed for 80–100 revolutions, either in the concrete mixer or in the ready-mix truck.
Compatibility with other admixtures: Sika® ViscoCrete®-1000 can be used in combination with other Sika admixtures and can be successfully used in mix designs utilizing supplementary cementitious materials.
Recommended Dosage
The typical dosage range for Sika® ViscoCrete®-1000 is 130-780 mL/100 kg (2-12 fl. oz/100 lb) of cementitious material.
For maximum water reduction, dosage rates up to 1170 mL per 100 kg (18 fl. oz/100 lb) of cementitious material may be used. At higher dosages, delayed setting time will likely occur. Dosage rates vary depending upon the amount of plasticity and/or water reduction desired. Slump, ambient temperature, water-cementitious ratio, mixing time and various concrete materials, such as type of cement and supplementary cementitious materials, will affect dosage rates. It is recommended to conduct trial mixes with the actual materials to determine the required dosage for optimum performance.
To the extent specialized materials (such as microsilica) are specified, extreme ambient project conditions are encountered, or other unusual project conditions require special consideration outside the recommended dosage, contact your Sika Canada Technical Sales Representative for further information.
