How a "surface texture" property can be simulated on a coarse aggregate, numerically ?

I am trying to develop a numerical aggregate model for a concrete specimen, to study the behavior of mechanical properties due to the variations of aggregate surface texture (same as surface...

Is there a relationship between the water-cement ratio and the porous band which is defined in corrosion studies (Delta 0)?

I understand the fact that when water cement ratio increases, the concrete microstructure will have higher hydrated gel pores. In corrosion studies in reinforced concrete, the porous band has a...

What is the relationship of corrosion rate Pr (micrometer/year) and the mass loss Wl(g) based on Faraday's Law of Corrosion?

In a paper, I saw Pr = (1.116x10^7 x WL)/(AxT) Pr = corrosion rate (um/year) WL= weight loss (g) A = Surface area (cm^2) T = Time elapsed (Hours) Can someone help me to derive this equation? Thank...
