Concrete Formation Using Fiber and Polymer

The use of fibres in brittle matrix materials has a long history going back at least 3500 years when sun-baked bricks reinforced with straw were used to build the 57 m high hill of Aqar Quf near Baghdad. In more recent times, asbestos fibres have been used to reinforce cement products for about 100 years, cellulose fibres for at least 50 years, and polypropylene, steel and glass fibres have been used for the same purpose for the past 30 years. The importance of fiber reinforcement is to carry the load along its length and also to provide stiffness and strength in one direction. Fibre reinforced polymer in this manner modify the compressive strength, tensile strength and flexural strength of concrete in a good amount and hence it sign as a good solution for enrichment concrete. Fibre reinforced polymer materials may be externally bonded or wrapped to the parent structure, hence they can be used for reestablishment works. In the present investigation he effect of Polyester fibre (Polymer at dosage of 0 %, 0.3 %, 0.6 %, 0.9 %, 1.2 % of cement) for compressive strength, flexural strength and split tensile strength of M25 concrete and test were carried out on basis of recommended codes for 7 days, 28 days and 90 days.
