Aggregates & Materials
M-Sand (Manufactured Sand)
// Definition
Crushed stone fines manufactured to act as fine aggregate. Replaces or supplements river sand and offers consistent gradation and shape.
M-Sand from VSI (vertical shaft impactor) plants has cubical particles and minimal silt, giving better packing and workability than river sand. Quality M-Sand conforms to IS 383 Zone II.

River Sand
Naturally occurring fine aggregate sourced from riverbeds. Increasingly restricted due to environmental regulations.
Fine Aggregate
Aggregate passing the 4.75 mm IS sieve — sand. Fills voids between coarse aggregates and contributes to workability.
Gradation
The distribution of particle sizes in an aggregate sample, determined by sieve analysis. Well-graded aggregates pack densely with minimum voids.
