APPLICATION OF CARBONATION MODEL FOR SERVICE LIFE DESIGN TO SERBIAN ENVIRONMENTAL CONDITIONS AND ENGINEERING PRACTICE M. Luković (1), I. Ignjatović (2) (1) Section of Materials and Environment, Faculty of Civil Engineering and Geosciences, Delft University of Technology, Delft, The Netherlands (2) Chair of Materials and Structures, Faculty of Civil Engineering, University of Belgrade, Belgrade, Serbia Abstract This paper highlights the application of carbonation model for service life design to local, Serbian environmental conditions and engineering practice. The basis of service life design using probabilistic approach and the deterioration model are presented. According to the data obtained from different sources, the varying range of each parameter typical for the local environmental and execution conditions (Belgrade, Serbia) was estimated. Therefore, instead of using probability distribution functions and characteristic values for some of the parameters, suggested mean values can be adopted for the local area. In addition, the influence of each parameter on the carbonation depth was estimated. 1. INTRODUCTION Since concentration of atmospheric carbon dioxide (CO 2 ) has been constantly increasing and that most of our structures are being built in urban environment, the carbonation process should be considered as one of the main causes for deterioration and the major concern of durability design of reinforced concrete structures nowadays. Therefore, carbonation induced corrosion is the focus of investigation presented in this paper. Traditionally, the durability design of concrete structures is based on implicit and experience based rules for materials, material composition, working conditions, structural dimensions, etc. According to the Serbian national design code BAB’87 [1], these requirements are related to the type of environment exposure, crack width limitation and minimum concrete cover as main ‘deem to satisfy’ design rule. On the other hand, additional limitations such as maximum water to cement ratio, minimum cement content, air content and cement type are proposed by European design code [2]. The purpose of all these rules is to secure the robustness of the structure, although it is not possible to conduct durability design for intended service life or to give explicit relationship between performance and remaining Second International Conference on Microstructural-related Durability of Cementitious Composites, 11-13 April 2012, Amsterdam, The Netherlands
