Types and properties of Fiber Reinforced Concrete

Introduction

Concrete is widely used all over the world for many construction purposes. This concrete is undoubtedly the most reliable material used in the world of construction, but it lacks certain properties. It often undergoes cracking due to various reasons like insufficient curing, rapid gaining of strength, shrinking, bleeding and segregation and many more. Cracking is present in almost all types of concrete but the main difference between fibre reinforced concrete and ordinary concrete is the type of cracking. In ordinary concrete the cracking is sudden but this is not the case in fiber reinforced concrete. The cracking is not sudden as fiber reinforced concrete has a certain level of durability which gives sufficient time and indication that the structure is about to collapse. This level of flexibility is adopted in concrete by the use of fibres made of steel, glass, polypropylene, polyethylene, etc. Further, here the properties and types will be discussed in order to have a view about such...
