Where R12 Is Used
High-Rise Buildings
Suitable for high-rise building construction, where high-strength concrete, improved pumpability, and reduced permeability are critical. Finer particle size enhances concrete density and supports durable structural construction.
Ports & Harbours
Designed for ports, harbours, marine structures, jetties, and coastal infrastructure exposed to aggressive environments. Helps produce dense concrete with improved durability suitable for long-term marine service.
Critical Infrastructure
Recommended for critical infrastructure projects such as nuclear facilities, dams, water-retaining structures, bridges, tunnels, and major public infrastructure. Controlled fineness supports consistent concrete performance.
High Performance Concrete (HPC)
Specifically developed for HPC requiring exceptional strength, durability, and particle packing. Micro-fine particles contribute to dense microstructures and improved long-term concrete performance.
