Hi, I want to estimate the service life of concrete. But I only have the sorptivity data and the bulk porosity data. Is there any model can be used to estimate the service life through sorptivity or porosity? I find most model are carbonation coefficient based or chloride ion penetration based. If not, can sorptivity be used to predict carbonation coefficient first?
yes , it is related to depth of carbonation compared to the concrete cover thickness
Sorptivity is used to determine the concrete capability to convey and absorb water using capillary suction. A reduction in sorptivity is a strong indication .
Ikhlass ibrahim Sydnaoui Rasha A Waheeb Thanks! The reduced sorptivity indicates the longer service life. But is there any prediction model that I can used to calculate the estimated service life?
yes, life 365 soft ware is a model to predict the service life of reinforced concrete buildings
NIST developed sorptivity-based service life estimates for the cases of sulfate attack and freeze-thaw degradation in the early 2000's. See:

Software is likely outdated with regards to most current OS's, but listed publications should still be relevant to your question.
