Research Plan and Goal • This project aims to design a long-lasting, high-performance rebar coating that effectively reduces corrosion at the interface between the rebar and the surrounding chloride-contaminated concrete. • A two-layer coating will be applied on steel rebar, with an inhibitor- loaded epoxy nanocomposite coating as the primer and a minerals-loaded epoxy-polyurethane nanocomposite coating as the top coat. • Electrochemical corrosion tests, surface analyses, and mechanical tests will be conducted to assess and elucidate the effect of different constituents on the protective performance of such novel epoxy-based nanocomposite coatings. ...

Introduction Clay, a natural source, with small loadings (%by weight) can substitute reinforces which are being used in polymers. The commercial importance of polymers has led to an strong investigation of polymeric material nanocomposites, of sizes varying from 1 to 100nm. These are being reinforced by particulates, fibers and layer inorganic fillers. In specific, in the case of layer inorganic fillers, taIc and mica are of maximum interest. There have been also recent advances in polymer/clay and polymer-layered silicate nanocomposite materials in recent times. Introduction Clay, in particular montmorillonite (MMT), a 2: 1 phyllosilicate as illustrated in Figure A, naturally ...
