  • FLAT PARTICLES ELONGATED PARTICLES OR FLAT

    Flat and elongated particles of coarse aggregates have a tendency to fracture more easily than other aggregate particles. When the coarse aggregate does fracture the gradation will likely change which may be detrimental to the mix. Additionally flat and elongated particles of aggregate for some construction uses may interfere with
