Investigation of freeze-thaw durability of pervious concrete

Abstract : Pervious concrete is a type of concrete that allows to drain water easily from the surface to the soil. It is characterized by a high permeability (~150-1000 L/min/m²), which is a consequence of its large connected inter-aggregates porosity. This structure is obtained by using single-sized aggregates and by limiting the use of fine aggregates. Even though pervious concrete presents substantial benefits, it is subject to various durability challenges such as freeze-thaw and clogging. In fact, in cold regions, pervious concrete structures are subjected to freeze-thaw cycles which deteriorate the material. The aim of the Ph.D. is first to understand the damage behavior of pervious concrete subjected to freeze-thaw in saturated conditions and in the presence of deicing salts, and second to optimize the mix design to increase the number of freeze-thaw cycles the pervious concrete can sustain before damage. In order to reach these goals, experimental and modeling approaches are considered. First, an experimental assessment of the freeze-thaw resistance of various formulations of decimeter-sized cubic samples of pervious concrete is performed. Every mix design contains an additive that potentially enhances the resistance to freeze-thaw. In terms of modeling, to understand why pervious concrete gets damaged when subjected to freeze-thaw cycles and the relevant physical processes that might be involved, we develop a poromechanical model relevant for freeze-thaw in saturated conditions and perform poromechanical finite-volumes/elements simulations on cemented aggregates subjected to freeze-thaw. We simulate the response of one aggregate coated with cement paste and two aggregates coated and bonded with cement paste.
