# mechanical properties of lightweight aggregates

Nov 01, 2013 · Assuming that the fracture mechanism is the same for single pellet compression and crushing resistance the following correlation between solid strength of single pellets and crushing resistance can be postulated: (18) C ⋅ 1 (ρ r e l a t i v e (c)) 2 / 3 ≈ σ c r i t where C is the crushing resistance, the solid strength, σ crit, is calculated by Eq
