Aggregate Testing

  • Bulk density, specific density, and specific gravity of aggregates (according to EN 1097-3, EN 1097-6, EN 1097-7);
  • Particle size distribution (granulometry) from 0.075 mm–31.5 mm (according to EN 933-1);
  • Absorption and moisture content of aggregates (according to EN 1097-6).
