2.4. Input Parameters. To investigate the effects of the mix condition on the chloride penetration in nonsaturated concrete, 0.4, 0.5, and 0.6 of the water to cement ratio were considered by using each porosity and pore size distribution, which were determined based on the mercury intrusion porosimetry (MIP).For the MIP test, mortar specimens with 0.4, 0.5, and 0.6 of and 2.15 of the sand to ...

Reinforced concrete structures under cyclic exposure to the corrosive environment such as the tidal zone as a part of marine structure entail the higher risk of steel corrosion. In this paper, chloride penetration in concrete exposed to the tidal zone was predicted using a combined moisture and chloride transport model. For the analysis of moisture transport, pore size distribution in concrete ...

01/01/2018  To investigate the influences of the tide level and mix condition on the chloride penetration in concrete, three types of daily drying time and w/c were reflected in the moisture and chloride profiles, respectively, as given in Figures 4 and 5. In these cases, 0.5 of w/c was used as a mix condition for the simulation in Figure 4, and the medium tide level was used as a boundary condition for ...

This work documents a numerical model, the objective of which is to predict the chloride penetration through saturated concrete. The model solves the Nernst–Planck/current law equations and accounts for the chloride interactions with the solid phase. In addition to boundary conditions, it requires a set of five experimental characteristics available from a single sample of material namely ...
