“…From this point on, an abrupt increase of strains is observed as a result of a combination of a chemical phenomenon (the additional formation of ettringite) and a mechanical phenomenon (release of stress due to cracking). This combined effect may explain the sudden increase in the estimations provided by Tixier and Mobasher [34] in Fig. 11.…”

A diffusion -reaction numerical model is proposed to simulate the response of concrete exposed to external sulfate attack. Diffusion properties are modified based on the strain reached and the ratio of porosity filled by ettringite. A direct and intuitive approach is proposed for the consideration of the diffusion in a cracked porous media based on the constitutive law of the material. A methodology to compute expansions based on a more realistic consideration of the concrete porosimetry is presented, by which it is possible to distinguish different strain contributions from different pore sizes. The described approach also allows the consideration of different capacities to accommodate expansive product for each pore size considered and the faster filling rate existent in small pores. Critical parameters of the numerical model developed are recognized and

“…The difference in the proposed models can be observed in their method of estimating macroscopic expansion rate. In one of the approaches, stress-strain curves are changed in association with damage factor defined by an expansion strain and expansion rate which can be calculated from stress and elastic modulus at certain expansion strain and averaged area (Krajcinovic et al 1992;Schmid et al 1999aSchmid et al , 1999bTixier et al 2003aTixier et al , 2003b. Another approach is that, expansion rate is calculated by structural analysis introduced by expansion strain as initial strain (Idiart et al 2011).…”

“…In general, the proposed diffusionreaction model is composed of a mass transfer term and a reaction term. With regard to mass transfer modeling, diffusion model considers interaction of coexistence ion (Maltais et al 2004;Glasser et al 2008;Schmid et al 1999aSchmid et al , 1999b or brief diffusion model of sulfate ion (Krajcinovic et al 1992;Tixier et al 2003aTixier et al , 2003bIdiart et al 2011;Ikumi et al 2014). In addition, some 1 researcher take account for the effect of moisture transfer against sulfate attack in order to evaluate the influence of drying condition (Maltais 2004;Glasser 2008,).…”

“…In comparison, chemical reaction model can calculate the change in reactant and precipitation from molar ratio of chemical reaction equation. In this approach, chemical reaction is defined by certain minerals and sulfate ion, and reaction rate constant is set to fit in actual phenomena (Krajcinovic et al 1992;Tixier et al 2003aTixier et al , 2003bIdiart et al 2011;Ikumi et al 2014).…”

In this paper, the transformation of solid phase and expansion cracking behaviors due to sulfate attack were evaluated by using RBSM-Truss Network Model. This analysis was constructed by combining a hydration model, a diffusionreaction model, and a crack propagation model in order to evaluate the influence of feedback system of ion transfer through cracks on transformation of solid phase and expansion cracking behavior due to sulfate attack. As a result, the proposed model can predict the change in phase assemblage and physical properties due to hydration process and the change in the transformation of solid phase and the distribution of sulfate ion due to sulfate attack. It was found that expansion crack can affect the diffusion process and expansion cracking behavior as the crack behaves as a buffer of sulfate ion.

Lots of concrete structures are located in marine environment, the durability damage of these structures is often the result of the interaction of load, environment, and other factors. In this paper, tests for the stress–strain relation of concrete under the coupled effects of sustained loading, sulfate attack and dry‐wet cycle were conducted. Then, based on the damage stress–strain relation model of concrete under sulfate attack, a calculation method for the stress–strain relation of concrete under the action of sulfate attack and dry‐wet cycle was proposed. Meanwhile, by taking into account the effect of creep on the stress–strain relation of concrete, a time‐dependent stress–strain relation model of concrete was presented. Numerical simulations by the time‐dependent stress–strain relation model demonstrate that the calculated results agree well with the experimental data. Furthermore, the rationality and applicability of the time‐dependent stress–strain relation model were also discussed.
