KingGrout GP50®
General purpose non-shrink cementitious grout.
Overview
KingGrout GP50 is pre-mixed, pre-packed chloride free cementitious grout. It contains cement, selected additives, well graded, and non-reactive aggregates and is designed to give excellent flow properties, shrinkage compensation, frost resistance, and high compressive strength.
Applications
- KingGrout GP50 is ideally designed for use in the following applications:
- Machine beds
- Stanchion bases, struts, railings, and guardrail assemblies
- Filling of shutter tie rod openings
- Anchoring of tie bars, and bolts
- Pile top re-profiling
Advantages
- Good non-shrinkage characteristics
- Extremely dense and low permeability
- High early strength development allowing for rapid installation
- High flow can be poured or pumped into variable gap widths down to 10 mm
- Easy to apply, single component which require only addition of water
- STANDARDS KingGrout GP50 complies with ASTM C1107, Grade A

| Notes | Typical properties @ 3.6 litre/25 kg @ 25ºC. Compressive strength @ 1 day is under restrain. Compressive strength and Flexural strength @ 7 & 28 days are under wet cure @ 25⁰C. Mixing time should be continued for 3 minutes until uniform consistency is obtained. PLACING AND FINISHING | — |
| Under Base plate | Enough material should be available to achieve continuous fill and to complete the work. Pouring of the mixed grout should be started from one side only to avoid air entrapment. To obtain maximum flow distance, a side shutter feed between 100 - 250 mm high should be erected and used to build the required head. | — |
| Formwork | As the mixed grout poses high fluidity characteristics, all formwork and shutters should be water tight. This can be obtained by sealing underneath the formwork and at the joints by using an appropriate mastic. The unrestrained areas should be kept to a minimum due to the expansive nature of KingGrout GP50. | — |

Usage & Packaging
KingGrout GP50 is available in 25 kg bags. KingGrout GP50 can be applied in a single layer at thickness between 10 - 100 mm. For greater thickness, an 8 – 12 mm washed aggregate should be added at a ratio of 15kg of washed aggregate to 25 kg of KingGrout
Approximately 13.5 – 14 litre/25 kg bag depending on consistency.
Shelf life is 1 year when stored under cover, out of direct sunlight and protected from extremes of temperature
