Meso-Structure and Transport Performance of Near-Surface Concrete

Abstract:

Transport performance of near-surface concrete is a main factor affecting the durability of concrete structures. Meso-structure of near-surface concrete and its effect on permeability were investigated. The near-surface concrete was divided into several layers, and by considering the dilution effect, the tortuous effect, and the interfacial transition zone effect on permeability caused by aggregates, together with hardened paste permeability, a computational frame for permeability determination of near-surface concrete was established.
