Book Description

This Digest provides an overview of the physical and chemical degradation processes that can affect concrete buildings and infrastructure. It outlines the main considerations in designing, specifying and executing durable concrete in order to ensure that it continues to perform in aggressive environments without premature deterioration or unplanned maintenance. The Digest will interest developers, asset owners, engineers and specifiers who wish to gain a broad understanding of the factors controlling the performance  of concrete structures in aggressive environments

Contents:

Introduction
Factors contributing to the deterioration of concrete structures
Reinforcement corrosion
-General

-Specification of concrete to resist reinforcement corrosion
External chemical attack
-General
-Sulfate attack
-Thaumasite formation
-Acid attack and erosion
-Seawater attack on concrete
-Biological attack
-Resisting external chemical attack (Sulfate attack. Acid attack and other aggressive agents)
Internal chemical attack
-Alkali–silica reaction
-Delayed ettringite formation
-Calcium aluminate cement
-Environments in which concrete will not deteriorate
Physical processes
-Freeze–thaw damage
