Description
HI PLAST – SCA – Alkali Free Shotcrete Accelerator is a liquid, high performance accelerator specifically engineered to give high early and ultimate compressive strengths in shotcrete applications. This liquid accelerator blends easily and completely and can be injected directly at the shotcrete nozzle, permitting low dosages (3% –7% by weight of cement) .
USES
Hi Plast-SCA is suitable for both wet and dry applications and has been specifically designed for securing and stabilising rock and slopes in tunnel and subway construction, Mines, Soil stabilization, and Bridge Repairs.
ADVANTAGES
- Alkali free.
- Quick setting and achieves high early strength.
- Provides excellent bonding characteristics.
- Improves compressive strength of shotcrete.
- Provides superior performance on wet ground and at low temperatures.
- Powerful enough for multiple, thick sprayed linings
- Effective at low doses
PACKING
Hi Plast-SCA is available in 250 HDPE Barrels.

DIRECTIONS
Surface preparation
Ensure the surface is clean and free from loose material. For optimum bonding, dampen the surface with high pressure water, prior to application.
Dosage
The dosage rate of Hi Plast-SCA will vary depending on application temperature conditions,required thickness, the quality of cement used, and target early strength development and setting time. Hi Plast-SCA is generally dosed at rates ranging from 3% to 7% by weight of cement.
APPLICATION
Hi Plast-SCA is added through the shotcrete nozzle.
Ensure the dosing pump, hoses and other components are thoroughly cleaned with water both before and after use . Failure to do so could cause pump blockage and/or breakdown.
SHEL LIFE
1 year in original, unopened container.
SAFETY
During use, avoid contact with the skin and eyes. Wear protective gloves and eye protection when handling the product. In case of contact with the eyes rinse with plenty of fresh water and seek medical advice.
