Corrosion , Repair

and Maintenance of Structures

Chapter 1 .0 Introduction

In many places around the world , there are structures that have existed for a long time and either they are still being used or they are simply left there standing with no use at all to the public . For that reason these structures that are no longer being used must be rehabilitated in for them to be re-used in some way . When pertaining to structures to rehabilitate means `to restore , to repair , to rescue from a state of corrosion . The idea

of rehabilitation came after the World War II when old buildings were starting to show damage through time or damage from human intervention . The easiest way to fix them was to restore them That process today is very widely used and is a very familiar process which applies to almost every structure on earth - from structures that need to be repaired to structures that need to have a completely different look or structures that need to expand . It can also be applied on structures that need to be strengthened in to prolong its life for another set of years

Rehabilitation of structures , as a process , can save time , money and work . That is because there is no need for the demolition of an already existing structure and building again from scratch . Simply put rehabilitation means that some changes or improvements need to be made This process also saves space since there is no need for a new area in to build a new structure

In this , I am going to divide this process into three stages . The first stage is the corrosion , where I am going to explain all the factors that lead to corrosion of structures and how it affects them The second stage is the part of repairing a structure after it has undergone corrosion . In this stage , I will mention ideas and ways that have been developed through the years which can be applied to existing structures that have been affected by corrosion . The third and final stage that will be discussed in this are the ways on how to maintain a structure and how to prevent further deterioration after repair in to minimise its cost efficiency

Chapter 2 .0 Corrosion Factors

Introduction

Corrosion is caused by a lot of factors and it often results to the failure of a structure . All these factors have to be studied in to prevent structure failures . Corrosion , most of the time , is caused by extreme weather conditions but it is not the only factor that causes corrosion and it is also not the main cause of structure failures . By analysing corrosion and explaining how it happens , we can separate it in different areas

Factors of Corrosion

Corrosion depends on many factors which we will focus on such as material , environment , stress , temperature and time factors . These factors are dependent and interconnected with each other

Material Factor

The material factor has to do...
