Compaction and seepage properties of crushed limestone ...

2015-12-18 · Crushed limestone samples need to be completely saturated by water before each experiment and at the beginning of seepage. They were saturated again under low axial pressure. The testing fluid was water with a density of (rho_{w}) = 1000 kg/m 3 and kinetic viscosity of μ = 1.01 × 10 −3 Pa s at room temperature state.
