Application of the colorimetric method to chloride diffusion evaluation in concrete structures

The influence of combined application of two SCMs on the corrosion and acid attack durability of mortars

“…Some other investigations worked with similar aspects, and they were studied to compare with our results [15][16][17][18][19][20][21]. In this recent research different substitution ratios of the cement were followed, and the main properties of the mixture of silica fume and metakaolin (when they were used together at the same mixture) were additionally investigated.…”

Método colorimétrico por aspersión de nitrato de plata para la evaluación de la penetración de cloruros en concreto: estado del arte

“…The most representative current method to determine current status is based on the second Fick's Law. But this is a time consuming procedure and to improve this situation, accelerated methods, as proposed by ASTM C 1202/05, have being used in association with the identification of chloride penetration depth (KIM et al, 2013). There are several methods to identify and quantify free and total chlorides along the depth of the concrete (chlorides profile), such as gravity (PEREIRA & CINCOTTO, 2001;SILVA, 2006).…”

“…For the sake of determination of the chloride profile -which requires cutting or drilling, milling and chemical analysis of specific samples -once held towards various equipment and analysis timetable (He et al, 2011). In contrast, the colorimetric method based on AgNO3 for measuring penetration depth of chlorides in the cement matrix is practical and fast (JUCÁ, 2002;MECK & SIRIVIVATNANON, 2003;YUAN et al, 2008;FRANCE, 2011;HE et al 2011;MOTA, 2011;KIM et al, 2013). Yet, its efficiency and application conditions must be well driven and selfunderstood to perform the method and to provide the possible application of advantages of such technique.…”

“…HE et al, 2012;. FRANCE, 2011;KIM et al, 2013). In this context, the purpose of this article is to evaluate the applicability of the colorimetric method towards silver nitrate spraying once analyzing and comparing researches conducted and published.…”

Experimental Investigation of Chloride Ion Penetration and Reinforcement Corrosion in Reinforced Concrete Member

“…Similar process was done after 60 and 90 days salt ponding of other specimens successively. This process is known as colorimetric process ( [10], [11]) which is less time consuming and simpler than other methods. …”
