PRi Rock Bolt Grout should be mixed with approximately 1 gallon of water per 50 lb (22.7kg) bag. The amount of mixing water may vary due to grout temperatures. Additional variations in mixing water may be required due to pumping and placement requirements.
- Never leave mixed grout in the pump for extended periods of time.
- Do not add admixtures or fluidifiers.
- Store material in dry facility.
- Rate of strength gain is affected by temperature extremes.
- In all cases, consult the Material Safety Data Sheet before use.
