Where R5 Is Used
Ultra High Performance Concrete (UHPC)
Specifically developed for UHPC requiring exceptional strength, durability, and particle packing. Ultra-fine particles contribute to dense microstructures and improved long-term concrete performance.
Construction Chemicals
Widely used in high-performance construction chemicals including precision grouts, repair mortars, injection grouts, tile adhesives, and cement-based specialty formulations.
Precision Precast
Suitable for precision precast concrete applications where superior surface finish, dimensional accuracy, and high early performance are required — premium architectural and structural precast components.
Alternative to Micro Silica & Metakaolin
Can serve as an alternative or partial replacement for micro silica and metakaolin in selected high-performance concrete and construction chemical applications, subject to mix design validation.
