KingAdd 50CW®
Accelerating admixture for unreinforced concrete and masonry.
SpecWorld has the Spec Pack, CSI specification and drawings for registered specifiers.
Overview
KingAdd 50CW is a calcium chloride based accelerating liquid admixture used to accelerate the early strength of unreinforced concrete and masonry.
Where to use
KingAdd 50CW is ideally designed for use in the following applications:
- Accelerating cement hydration which allow the concrete to resist frosting when it is at early stage.
- Unreinforced concrete flooring.
- Concrete brick, roofing tile, concrete pipes and dry- cast products.
- Early form work release.
- Segmental retaining wall systems.
Why use it
- Improves compressive strengths at early stage.
- Extends the mould life.
- Improves frost resistance at early stage.
- Speeding the production by enabling earlier release of precast moulds.
- Produces more defined edges.
COMPATIBILITY
KingAdd 50CW can be used with ordinary cement and rapid hardening cement but not with high sulfate and high alumina cement.
KingAdd 50CW should not be used in conjunction with other admixtures unless KINGKRETE technical department approval is obtained.
