INTRODUCTION

During the recent past , the problem of early deterioration of concrete structure has posed a serious problem all over the world. In India also, this problem is being witnessed in the past few years, especially in coastal and industrial area as well as in other aggressive environments.

WHAT IS DURABLE CONCRETE ?

Durable concrete can be defined as one that is designed, constructed and maintained to perform  satisfactorily in the expected environment for the specified designed life.Generally, concrete suffers from more than one causes of deterioration, which is generally seen in the form of cracking, spalling, loss of strength, etc. It is now accepted that the main factors influencing the durability of concrete is its impermeability to the ingress of oxygen, water, carbon dioxide, chlorides, sulphates, etc. for cracks and other defects, sampling, measurement of concrete cover and assessing the material strength. The intensity of damage can be assessed on the data collected through Various investigations including Non Destructive techniques.
