Influence of sulphates on chloride diffusion and the effect of this on service life prediction of concrete in a submerged marine environment

Mathias Maes UGent, Robby Caspeele UGent, Philip Van den Heede UGent and Nele De Belie UGent (2012) IALCCE 2012 : proceedings of the third international symposium on life-cycle civil engineering. p.899-906
abstract
Single-ion attack by chlorides and multi-ion attack by chlorides and sulphates were compared with respect to the full probabilistic service life prediction of concrete structures, according to fib Bulletin 34. Especially the influence of sulphates on the chloride diffusion coefficient was investigated more thoroughly. Four concrete mixtures were tested, two Portland cement concretes and two blast-furnace slag concretes. Migration tests and natural diffusion tests were executed, based on NT build 492 and NT Build 443, respectively. Consequently, chloride migration and chloride diffusion coefficients were calculated. Based on the experimental results, the difference between both diffusion coefficients, measured after single-ion attack of chlorides as well as after multi-ion attack of chlorides and sulphates, is obtained. Finally, an input parameter was added to the service life prediction model taking into account the effect of the sulphate content. Additionally, the ageing factor and the transfer parameter were modified.
