Service life forecast for concrete

Overview

Concrete structures are exposed to complex actions with an influence on durability that may lead to substantial damage during their service life, which has been increasingly observed in transport infrastructure in the recent past. Service life forecasts provide the opportunity to estimate the expected progression of damage in concrete in order to initiate timely maintenance and repair measures. Service life forecasts essentially rely on damage models and probabilistic methods, such as specified in the fib Model Code for Service Life Design [1]. This paper outlines current practice with...
