摘要

A material law for low-sulfate shotcrete is set up in the framework of thermodynamics of reactive porous media. Two reactions with regards to kinetics are considered: the calcium aluminate hydration, lasting several minutes, and the calcium silicate hydration, lasting several days. The corresponding Finite Element formulation is discussed afterwards. Finally, results from the analysis of a shotcrete tunnel shell are presented.
