MasterRheobuild® 834

Description

USES
Sikament® RB 834 significantly enhances the properties of both fresh and hardened concrete, and is ideal for:

• Microsilica concrete
• Mass concrete pours
• Ready-mixed concrete
• Long-distance transport
• Pumped concrete
• Casting in hot climates

CHARACTERISTICS / ADVANTAGES

• Reduced thermal peaks
• Extended workability for longer periods
• Reduced pumping pressure
• Delayed setting for extended workability
• Increased ultimate strengths
• Lower permeability
• Improved durability

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
• Total Chloride Ion Content: < 0.2%

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.
