Where R25 Is Used
RCC Applications
Developed for Reinforced Cement Concrete applications where improved workability, reduced permeability, and enhanced long-term strength are essential. Suitable for residential, commercial, and industrial reinforced concrete structures.
General Precast
Ideal for General Precast Concrete products such as pipes, panels, kerbs, culverts, retaining blocks, and structural precast components. Finer particle distribution improves mould finish, dimensional accuracy, and production consistency.
Mass Concrete
Performs well in Mass Concrete applications by reducing the heat of hydration and improving long-term durability. Suitable for large concrete pours where temperature control and crack reduction are important considerations.
Roads & Highways
Widely applicable in Roads and Highway Construction, including bridges, flyovers, retaining walls, and pavement structures. Enhances concrete durability, improves workability, and contributes to longer service life under heavy traffic.
