Aggregates are inert granular, substances like either sand gravel or crushed stone which are an important component in concrete, alongside water and portland cement. Aggregates must be pure, hard, solid particles free from ingested chemicals or adhesives of clay as well as other fine materials for a good concrete mix that could trigger the concrete to deteriorate.
