APPLICATION INFORMATION

• Recommended Dosage: The optimal dosage of Sikament® RB 834 should be determined through trial mixes. A recommended starting range is 800ml to 2000ml per 100kg of cementitious material. For high-performance concrete, dosages up to 2000ml per 100kg can be used, subject to site-specific trials.
• Compatibility: Sikament® RB 834 is compatible with all types of cement and most air-entraining agents that meet ASTM standards. For concrete exposed to freezing and thawing cycles, it is recommended to use Sikament® RB 834 along with SikaControl®-720 AER (air-entraining agent).
