GRM only uses specified aggregates according to the current local and international standards.

GRM takes extreme care in the selection of aggregate properties, Characteristics that are considered, include:

  • grading
  • strength (crushing impact & abrasion values)
  • particle shape and surface texture
  • Relative density & water absorption
  • Soundness

Raw-materials aggregate, cement, slag and admixture are ordered on a daily basis allowing to cope up with continuous production. All raw-materials are thoroughly inspected upon delivery and samples are taken at random and tested in accordance with the relevant industry specifications for any obvious deviation or abnormality.

All raw-materials are checked and tested as per our Quality Control Procedure.
