The fibre like asbestos, glass, plastic, steel, jute can be used as reinforcement in concrete to increase various And also to know whether this concrete is economical for all purposes.įibre reinforced concrete (FRC): When Concrete mixture is prepared by adding individual or combination of different types of fibre in it, then such formed concrete is termed as Fibre reinforced concrete. We have selected this topic as to know the different characteristics of fibre reinforced concrete in terms of compressive strength, workability, durability, etc. Polytechnic, all the students are given opportunity to undergo in project as part of their syllabus. KeywordsFibre Concrete, glass fibre concrete jute fibre concrete, steel fibre concreteĪs per the education pattern followed in M.H.S.S. Fibres are currently being specified in tunnelling, bridge decks, pavements, loading docks, thin unbonded overlays, concrete pads, and concretes slabs. Fibre Reinforced Concrete (FRC) is gaining attention as an effective way to improve the performance of concrete. Fibre reinforced concrete has so far been successfully used in slabs on grade, architectural panels, precast products, offshore structures, structures in seismic regions, thin and thick repairs, crash barriers, footings, hydraulic structures and many other applications. The usefulness of fibre reinforced concrete (FRC) in various civil engineering applications is indisputable. They are useful in shotcrete and in thin overlays that are not sufficiently thick to accommodate reinforcing bars, and they have good resistanceto impact, vibration, and blasts. The fibres are added during concrete production. Fibres are not intended as primary reinforcing. The fibres are useful in providing greater resistance to plastic shrinkage cracking and service-related cracking.

Incorporation of steel fibres help in giving a longer deflection softening than a sudden brittle failure, thus proves its ability to increase energy absorption capacity and improving cracking behaviour.

The cracks began from the external ribs and propagates toward the internal rib. First cracks for all slabs occurred at the topping. The flexural strength of ribbed slab with 100 mm topping shows similar loading carrying capacity with the 75mm topping while 50 mm gave the lowest ultimate loading.

Three equivalent samples of ribbed slabs were prepared for this study with variations in the topping thickness of 100, 75 and 50 mm. This study is performed to investigate the behaviour of SFRC as the main material in ribbed slab, omitting the conventional reinforcements, under four-point bending test. However, in order to overcome the drawbacks in the construction process, the application of steel fibre reinforcement concrete (SFRC) is seen as an alternative material to be used in the slab. Ribbed slab provides lighter slab than an equivalent solid slab which helps in reducing the weight with its voids.
