Abstract

This works aims at studying, through the Monte-Carlo method, the influence of the leaching kinetics parameters spatial variability on the lilfespan of a concrete structure. The considered structure is a tunnel for nuclear waste disposal. It is observed that the expected value for the lifespan estimated when considering the material spatial variability is significantly lower than the lifespan estimated with a single simulation considering uniform parameters fields, equal to the expected value for each parameter.
