Where R12 Is Used

High-Rise Buildings application

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 and Harbours application

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 application

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.

Construction Chemicals application

Construction Chemicals

Used in construction chemicals including cementitious grouts, repair materials, dry-mix products, and specialty cement-based formulations. Micro fine particles improve packing density, workability, and performance.
