| Abstract: |
Durability represents a crucial issue in the evaluation of safety and serviceability for reinforced concrete structures. Carbonation-induced corrosion is a complex process, which involves several phenomena with different nature at the micro-scale level. Many studies have already focused on carbonation-induced corrosion of natural aggregate concrete (NAC), leading to several prediction models to estimate carbonation depth. Less research is devoted instead on recycled aggregate concrete (RAC), about which limited experimental works analyzed carbonation coefficient in accelerated tests. This work presents a reliability-based analysis of carbonation resistance of RACs, applied on experimental carbonation coefficients derived from literature, and on the full probabilistic method prosed in fib Bulletin 34. |
