Sidhya® Visco PC 152
High Performance Superplasticizer for Precast Concrete
Description
Sidhya® Visco PC 152 is a high-performance low viscosity product to produce high quality precast concrete. The product is a unique combination of the latest generation low viscosity polymers which improves the water reducing and cement dispersion properties of the product. Sidhya® Visco PC 152 presents exceptional improvement in early strength by initiating faster hydration of concrete. Sidhya® Visco PC 152 also improves strength development and slump retention properties of concrete.
Applications
Sidhya® Visco PC 152 is a high-performance water reducer designed for high early strength and good slump retention in precast concrete. Precast elements such as Hollow core slabs, Block, cement tiles, Kerbstones and other décor elements can be produced by using Sidhya® Visco PC 152. The product is mainly used for the following applications:
- Production of high-quality Precast Concrete.
- Provides high early strength for quick stripping times.
- Used in the production of precast concrete with high early strength.
- Precast Concrete requires faster setting time.
- Precast Concrete with high durability requirements.
- Low viscosity concrete with high pumping precast concrete requirements.
Mixing
Sidhya® Visco PC 152 is not recommended to be added along with dry aggregates and cementitious materials. Sidhya® Visco PC 152 should be added to the concrete mixer post 70% of the mixing water has been added. To achieve the optimum performance, the product is recommended to have minimum wet mixing period of 60 seconds depending on the mixing conditions.

Advantages
Sidhya® Visco PC 152 improves the workability of the concrete and surface finish of precast concrete elements. Sidhya® Visco PC 152 improves the dispersion of cementitious materials and provides the following advantages:
- Provides high early strength without increasing cement content.
- Reduction in De-shuttering time and hence increasing production e6iciency.
- Improvement in early strength of concrete.
- Increase resistance to carbonation.
- Improvement in durability properties of concrete.
- Improvement of workability of concrete.
- Reduces shrinkage and creep.
Dosage
The recommended dosage of Sidhya® Visco PC 152 should be between 0.2% to 2.0% by weight of cementitious. E6ects of over dosage can delay the setting time and lead to bleeding and segregation in fresh concrete properties.
The optimum dosage of the Sidhya® Visco PC 152 should be determined by preliminary trials at site. The dosages above recommendations can be used if agreed by the client and consultant for special applications along with consultation of Sidhya® technical team.
Compatibility
Sidhya® Visco PC 152 is compatible with all types of cement and binders such as GGBS, Ultra Fine GGBS, Micro silica, Fly ash and Metakaolin. Sidhya® Visco PC 152 when using along with other Sidhya® products should be added separately and must not be blended prior to addition.
Important: It is important to conduct preliminary trials when using more than one admixture. Do not combine Sidhya® Visco PC 152 with any Naphthalene based admixtures.
Technical Compliances
Sidhya® Visco PC 152 conforms to the requirements of IS 9103: 2007, ASTM C494 Type F & G & BS EN 934-2.
Storage
Sidhya® Visco PC 152 has a shell life of 12 months provided the temperature is kept between +1.00C to +50.00C. Please contact Sidhya® technical team if the product falls outside the temperature range.
