Flocrete R666
Retarding and water reducing admixture
Flocrete R666 is formulated from selected polymers specially designed to enable the water content of the concrete to perform more effectively.
This effect can be used to improve workability, to increase ultimate strengths or to facilitate a reduction in the cement content while sustaining and improving mix properties. Flocrete R666 has retarding properties; this effect can be used in concrete where high cement content or high temperatures are involved, or where extended setting time is required.
- Improved workability reduces placing and compaction problems.
- Workability retention for long distance concreting.
- Cold joints can be avoided by extending initial and final concrete setting time.
- Cement saving without affecting strength.
- More durable concrete as a result of reduction in permeability and lower water to cement ratio.
- Hot weather concreting.
- Where workability retention or retardation are required.
- For Roller Compacted Concrete (RCC).
Flocrete R666 is available in 225 kg drums and 1000 litre bulks supply.
Flocrete R666 has a shelf life of 12 months from date of manufacture if stored at temperatures between 2°C and 50°C.
The guidance dosage of Flocrete R666 is 0.10 - 0.55 litre per 100 kg of cementitious materials in the mix, including GGBFS, PFA or microsilica.
Representative trials should be conducted to determine the optimum dosage of Flocrete R666 to meet the performance requirements by using the materials and conditions in actual use.
Flocrete R666 complies with ASTM C494, Type D, IS 9103:99 and BS 5075, Part 1:1982.
