Can someone suggest reliable data sets or relations that can obtain the strength properties of cement paste materials (cement+sand+water)?

I am currently modeling concrete material behavior under different loading conditions, and it requires a series of realistic input material properties assignments for cement paste matrix. In order...

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...

Can someone suggest me a deterministic way to predict the service life of existing RC structures to a higher accuracy under corrosion due to Chloride?

I have been looking for some models for Service Life (SL) prediction and have been able to find such models that gives a certain number for the SL. However, for such models, i have some doubts and...
