KingAdd 50RP®
Retarding and water reducing admixture.
Overview
KingAdd 50RP 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. KingAdd 50RP 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.
Applications
- Roller compacted concrete (RCC)
- Hot weather concreting
- Where workability retention or retardation are required
- To produce high quality concrete of improved durability and water tightness
Advantages
- 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
- Higher strength with same cement content
- Cement saving without affecting strength
- More durable concrete as a result of reduction in permeability and lower water to cement ratio
- COMPATIBILITY KingAdd 50RP can be used with all types of Portland cement and cement replacement materials. KingAdd 50RP is compatible with other KINGKRETE admixtures used in the same concrete mix. If more than one type of admixture is to be used in concrete mix, they must be dispensed to the concrete separately
- STANDARDS KingAdd 50RP complies with ASTM C494, Type B and D and with BS 5075, Part 1
