Applications:
– Designs requiring very low water-to-cement ratios.
– Ready-mix concrete and precast concrete elements.
– Prestressed concrete.
– Production of high-workability, durable, and high-slump concrete.
– Self-compacting concrete.
Benefits:
– Increased early-age compressive strength.
– Enhanced concrete impermeability.
– Reduced need for vibration, minimizing manual labor.
– Improved bond strength between concrete and steel reinforcement.
– Higher flexural strength of hardened concrete.
– Chloride- and nitrate-free, ensuring no harm to concrete.
– Compatible with microsilica- or fly ash-containing concrete mixes.
Dosage:
0.3% to 0.8% by weight of cement, varying based on target strength, weather conditions, compaction, and rebar spacing.
Application Method:
1. For ready-mix concrete: Add to pre-adjusted water-content concrete and mix for 2 minutes.
2. Step-by-step method:
– Mix aggregates, sand, and cement with 50–70% of water for 15–30 seconds.
– Add the recommended dosage of RW Super Plast 522 and mix at high speed for 1 minute until homogeneous.
– Gradually add remaining water (if needed) to achieve desired workability.
Important Notes:
– Overdosing (2–3 times the recommended dosage) may cause delayed setting, reduced 24–48 hour compressive strength, increased air entrainment, and altered properties.
– Never add directly to dry mix.
