Fosroc Conplast SP430 SRV — SNF Based Slump-Retaining Superplasticizer | Fosroc India (250 kg)
Fosroc Conplast SP430 SRV — SNF-Based Slump-Retaining Superplasticiser for Concrete
Fosroc Conplast SP430 SRV is a specialist SNF (Sulphonated Naphthalene Formaldehyde) based superplasticiser from Fosroc Chemicals India, engineered specifically for applications where extended workability retention is critical. The SRV designation stands for Slump Retaining Value — designed for RMC operations, long-haul transit concrete, and hot weather concreting where standard SNF admixtures lose workability before placement is complete. SP430 SRV maintains adequate slump for longer durations without compromising strength development or durability.
Key Features
- Extended Slump Retention: Maintains workability for longer periods — critical for RMC transit and long-distance pumping
- High Water Reduction: Reduces mix water by 20–25%, enabling high-grade, durable concrete
- Hot Weather Performance: Particularly effective in high ambient temperature conditions common in India
- No Retardation Side-Effects: Provides workability extension without excessive set retardation at normal dosage
- Improved Pumpability: Cohesive, stable mixes with reduced pump friction
- Chloride-Free: Safe for reinforced and prestressed concrete
- IS 9103 Compliant: Meets Indian standard for concrete chemical admixtures
Applications
- Ready-mix concrete (RMC) — long transit and extended delivery windows
- Hot weather concreting — avoiding slump loss before placement
- Large infrastructure pours — bridges, flyovers, tunnels, dams
- Mass concrete — foundations, raft slabs, thick walls
- Pumped concrete over long horizontal or vertical distances
- Concrete requiring extended workability for complex formwork placement
