“…Ožbolt, Balabanić, Periškić, and Kušter (2010) developed a 3D numerical model for transport of capillary water, oxygen and chloride through the concrete taking into account the interaction between the non-mechanical processes and mechanical properties of concrete in order to investigate the influence of damage of concrete on depassivation time of reinforcement, the influence of concrete quality, cracking and water saturation in concrete on the current density (Ožbolt, Balabanic, & Kušter, 2011), the transient analysis of corrosion processes before and after depassivation and the corrosion-induced damage of steel reinforcement (Ožbolt, Oršanić, & Balabanić, 2014;Wang & Ueda, 2011) quantified the chloride diffusion coefficient of concrete by means of a meso-scale modelling method based on available experimental results from literature. Park, Kwon, and Jung (2012) proposed an analytical model for the evaluation of chloride behaviour in cracked concrete considering both chloride diffusion and water permeation in a Representative Element Volume.…”

The presence of cracks in reinforced concrete structures added to the chloride-induced steel corrosion is worldwide one of the major causes of deterioration of reinforced concrete structures, producing loss of structural strength and stability. This study deals with the influence of artificial cracks on chloride penetration in mortar specimens by presenting both the experimental and the numerical results. The experimental results were obtained using chloride penetration tests on mortar specimens of different sizes, with and without artificial cracks, subjected to chloride exposure. Numerical results were obtained using transient finite element analysis by simulating chloride mass diffusion. Comparisons between the results on chloride penetration concluded that the numerical ones obtained using the mass transfer modulus agrees fairly well with the experimental ones. In addition, the influence of certain crack parameters such as crack length, crack depth and also time exposure on chloride ingress was considered.

A comprehensive mathematical model which can simulate the entire corrosion process of reinforcement in concrete is proposed in this paper. e combined effect of carbonation and chloride ingress is also discussed in the mass transport module. Nonuniform corrosion distribution is employed for the study of mechanical damage in concrete. e link of ABAQUS with MATLAB is adopted for the numerical implementation of the developed model. e numerical results of an illustrative example indicate that the depassivation time of reinforcement, corrosion rate and expansion displacement, and cracking pattern of concrete all can be accurately predicted.

“…A recent study on crack emergence in the zone of adhesion steel-concrete was presented by Ožbolt et al [3] considering the effect of the different levels of corrosion using the 3D chemo-hygro-thermo-mechanical model. Basically this model considered the physical, electrochemical process with the concrete mechanical performance and also considered radial concrete resistance as linear elastic, and the adhesion zone as an isotopic area.…”

The present work provides a special contribution for assessment of the compressive strength of the concrete through a low-cost test. Here, an alternative pull out test is presented and an experimental campaign was carried out aiming the demonstrate the applicability of this novel methodology. Three different classes of concrete were performed, namely C20 (20 MPa), C25 (25 MPa) and C40 (40 MPa), each one with two variations of the reinforcement rebar diameter, that were 10 and 16 mm. In addition, references samples also were casted and submitted to compressive strength test by NBR 5739. The results found confirmed the applicability of the novel methodology for obtainment compressive strength of concrete.
