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 help me to find the remaining service life of an existing structure using a gravimetric method due to chloride admittance?

I need to assess the time taken for chloride initiation and also the time taken to form the first crack which causes an unacceptable level of damage to the structure.

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...
