Flo-Add C
Free flow non-shrink grout additive for post tensioned cables
Flo-Add C is a pre-packed powder consisting of selected admixtures and expansive material. The addition of Flo- Add C to grout mixes produces a high flow, non-shrink, and non-segregated grout. Flo-Add C reduces the water demand at the desired flow, producing high strength grout with low permeability and excellent bond to steel.
The low permeability grout produced with the aid of Flo- Add C will reduce the ingress of harmful agents and will protect the cables from corrosion.

- Will produce a non-shrink grout which is compensated for shrinkage and settlement in the plastic stage.
- Will produce a high flow grout without water bleeding.
- Will produce an extremely low permeability grout at low water to cement ratio.
- Reduces the ingress of harmful substances.
- High bond to steel.
- High initial and ultimate strength.
- Chloride free.
Flo-Add C is ideally designed for free flow grouting in post tensioned cables used in bridges, deck ducts, etc. It is also suitable for use in cable ducts and pre-stressed structural elements.
Flo-Add C is available in 6 kg bags.
Flo-Add C has a shelf life of 12 months from date of manufacture if stored at temperatures between 5°C and 35°C in original unopened bags.
Approximately 68 litre of mixed grout is obtained when mixing 6 kg Flo-Add C, 100 kg cement and 34 litre water.
The use of Flo-Add C enables grout mixes to comply with ASTM C1107, Type A.
