Porosity: Some characterization techniques
That is, both porosity and permeability are indispensable factors to favor the durability and useful life of elements with cement. The porosity, that is, the porosity volume fraction (Vp) can be defined as the fraction of the apparent specific volume of the sample (V) that is attributed to the pores [24], Eq. (9): (9) ϕ = V p / V. 4.

MINING ENGINEERING
For most rocks, porosity varies from less than 1% to 40%. The porosity of a rock depends on many factors, including the rock type and how the grains of a rock are arranged. For example, crystalline rock such as granite has a very low porosity (<1%) since the only pore spaces are the tiny, long, thin cracks between the individual mineral grains.

Engineering porosity of MIL-101(Cr) using solvation effect
This research reveals that the solvation effect influences the rate of crystal nucleation and growth, leading to variations in the ratio of micropores to mesopores and overall porosity in MIL-101(Cr)-XmM. The high porosity of MIL-101(Cr)-1.6 mM facilitates a higher diffusion rate of particles and exposes a greater number of alkaline sites.
