Where R34 Is Used
Portland Pozzolana Cement (PPC)
Widely used in PPC manufacturing as a high-quality supplementary cementitious material. Controlled fineness improves cement consistency, enhances long-term strength development, and supports durable blended cement meeting ASTM C618 and IS 3812 requirements.
PCC Applications
Ideal for Plain Cement Concrete applications including foundations, flooring, levelling courses, and non-reinforced concrete works. Improves workability, reduces water demand, and enhances long-term durability for large-volume concrete production.
Fly Ash Bricks
An excellent raw material for manufacturing Fly Ash Bricks with improved dimensional accuracy, higher compressive strength, and smoother surface finish. Consistent particle size helps produce quality bricks with reduced cement consumption.
Paver Blocks
Suitable for producing Fly Ash Paver Blocks used in roads, walkways, industrial yards, and landscaping projects. Controlled fineness contributes to improved mould filling, better surface finish, and increased strength.
