DAMAGE OF CONCRETE BY SULFATE ATTACK AND ALKALI-SILICA REACTION

摘要：

A holistic approach was adopted to examine concrete durability by taking into account both physical aspects (such as capillary porosity,micro-cracking,macrovoids) and chemical reactions. A temary representation of the complex damage process in reinforced concrete structures was used by examining the coexistence of the main three factors affecting the concrete durability: a) interconnected porosity; b) exposure to aggressive agents; c) presence of water.This model was adopted to examine two specific examples of the concrete damage dealing with the cement matrix and the embedded aggregates: sulfate attack of the cement matrix and alkali-aggregate reaction.
