Study the use of Polypropylene Fibers and Steel Fibres in Fibre Reinforced Concrete

Abstract

The concrete structures, after 1970 or after that made by use of high strength oriented steel bars with their maximum surface deformations, changed constituents and cement properties and different supplementary materials in cement and admixtures with their capacity of acceleration or deceleration. Now, in place of steel bars, fibers of steel, polypropylene, natural polymers etc. are in use [Anbuvelan, 2014]. The reasons for the demand are many, but as a building engineer, we have to think hard and architecturally using building materials. In anticipation of long-term sustainability, we need to be able to meet needs. Nowadays, the construction industry is turning to precast building materials and meeting pre-press and high-strength concrete delivery requirements. Also, engineers have to overcome these barriers, because in large concentrations, concrete sometimes mixes with different chemicals in the soil and makes changes in their properties. A variety of fiber materials other than steel, glass or other natural fibers have been developed and used in the industry to build reinforced fiber concrete. These fibers are classified as synthetic fibers, SNFRC editing. Synthetic fibers are man-made from R&D in the textile and petrochemical industries. Types of fiber that can be used in concrete matrices such as aramid, carbon, acrylic, nylon, polythene, polyester and polypropylene. Reinforced concrete concrete is a mixture that contains water, cement, composite and unfinished fibers of various shapes and sizes.
