KingGrout PT100®
Free flow non-shrink grout for post tensioned cables.
Overview
KingGrout PT100 is a pre-packed powder consisting of cement selected, admixtures and expansive material. KingGrout PT100 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 will reduce the ingress of harmful agents and will protect the cables from corrosion.
Applications
- KingGrout PT100 is ideally designed as 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
Advantages
- A non-shrink grout which is compensated for shrinkage and settlement in the plastic stage
- 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 and hydrogen free
- KingGrout PT100 can be supplied with an Anti- corrosion impregnating additive
- STANDARDS KingGrout PT100 complies with EN447

| Notes | Compressive strength @ 1 day is under restrain. Compressive strength @ 7 & 28 days is under wet cure. PLACING AND FINISHING In case of pumping, a suitable diaphragm pump must be used (screw and piston pump may also be suitable). The mixed grout should be pumped from one point only to eliminate air entrapment. The mixed grout should be pumped within 20 - 30 minutes of mixing. | — |
