Concrete is a construction material composed of Cement, fine aggregate, coarse aggregate, and water with or without admixtures. The concrete industry is one of the heaviest consumers of natural resources due to which sustainability of concrete industry is under threat. The biggest problem facing the concrete industry is the environmental and economic concern. In this research Paper I work on waste utilization on concrete , Use of waste and by-products as cement replacement, not only makes the concrete economically viale but also solve the problem of dumping the waste product which is a major problem in India.
Structures for a lifetime normally 80-100 years are planned and designed. Time-based effects or circumstances, such as a change of use, fire, earthquake, etc., may require an adjustment according to the state of the art during operation. Concrete is the world's most commonly used building material. This popularity of concrete has a huge environmental cost.
Fiber Reinforced Polymer
Fiber Reinforced Polymer (FRP) composites have been utilized in car, hardware, and advanced plane design for quite a few years, yet their application in solid building as a fortifying material is moderately later in root. Other than the advances in the field of improvement of new strands,
To Analyze Compressive strength by wrapping & coating 1.0 mm thick FRP. Considering coating length by 25%, 50% & 75% for different grades (M-20, M25, M-30).
III. LITERATURE REVIEW
Emon et al. (2017) In Bangladesh, a case study has been carried out using methods for fiber reinforcement of low-cost, Galvanized Iron (GI) cable cables, with the aim of improving concrete performance. GI cable is actually a gentle, zinc-coated metal cable. A variety of characteristics of GI cable fibers, e.g. tensile strength, bending capability etc. have been explored and comparable with the features of metal fibers in light of the appropriate ACI and ASTM rules to evaluate the suitability of GI cable fibers in addition to metal fibers
Praganya et al. (2016) The resistance of galvanized iron (G.I), the layer encased in concrete and sorptive force are determined in this document. G.I pipe in concrete was researched extensively over the last few years. Two different thicknesses are used for G.I plates. Beton has generally strong resistance characteristics, but due to its porous nature it has suffered harm even though it is of elevated power.

Compressive Strength Of Concrete Cubes
Concrete crushing strength is measured by rupturing different concrete cubes with CTM at a standardized loading speed. At the end of seven days the treatment was done and three cubes tested at the end of the 28 days the treatment was carried out for each set of concrete
Compression Test Results on Different cylinders after 28 days
Avg variations (%)
Specimen without confinement for compression test
Compression in 25% coverage
Compression in 50% coverage
Compression in 75% coverage
Effect of confinement on compressive strength,
1) For M-20 grade of concrete the Compressive strength increase by 5.50%, 13.7% & 21.3 % for confinement of 25, 50 & 75 respectively.
2) M-25 grade the Compressive strength increase (%) wrapping & coating by 6.90, 8.20 & 15.3 for length coverage in (%) 25, 50 & 75 respectively.
3) M-30 grade the Compressive strength increase (%) wrapping & coating by 5.90, 14.60 & 21.40 for length coverage in (%) 25, 50 & 75 respectively.
Thus, it can be concluded that the compressive strength increases with respect to confinement increment.
