Water Penetrability into Concrete Surface and Interface between Concrete and Repair Materials

Abstract

As water is related to many deterioration mechanisms affecting concrete structures, knowledge of water movement behavior in concrete is very useful for the effective maintenance of these structures. In this study, based on many data obtained from monitoring sensors embedded in concrete samples, it was clarified that properties of water penetration into concrete surfaces differ according to component materials, mixing proportions and curing methods of the concrete. It was also made clear that water penetration behavior into the interface between the concrete and the section repair materials depends on pretreatment methods applied before addition of the restoration materials.
