APPROVALS / STANDARDS
- ASTM C-494 Type A, B, D, & G
- BS 5075 Part 1
PRODUCT INFORMATION
- Packaging: Available in IBC containers and 210-liter drums
- Shelf Life: 12 months from the production date, if kept in unopened, undamaged, and sealed packaging
- Storage Conditions: Store at temperatures above +5°C. If frozen, thaw at +5°C or higher and reconstitute gently using mechanical agitation (do not use pressurized air). Keep out of direct sunlight and protect from temperature extremes.
- Appearance/Colour: Dark brown liquid
- Specific Gravity: 1.15 ± 0.02 at 25°C
- pH Value: > 6

APPLICATION INFORMATION
- Recommended Dosage: The optimal dosage should be determined via trial mixes. As a guideline, a starting range of 800ml to 2000ml per 100kg of cementitious material is suggested. For high-performance concrete, up to 2000ml per 100kg may be used, subject to prior site trials.
- Compatibility: Sikament® RB 834 is compatible with all types of cement and most air-entraining agents that meet ASTM standards. It is recommended for use with SikaControl®-720 AER (air-entraining agent) for concrete exposed to freeze-thaw conditions.
