  • Assessment of fines – Sand equivalent test ČSN EN 933-8+A1
  • Determination of particle size distribution – Sieving method ČSN EN 933-1
  • Determination of particle shape – Shape index ČSN EN 933-4
  • Assessment of fines – Methylene blue test ČSN EN 933-9+A1
  • Determination of abrasion resistance of aggregates by LA method ČSN EN 1097-2, art. 5
