DEVELOPMENT OF SUSTAINABLE FIBER REINFORCED SELF COMPACTING CONCRETE USING RECYCLED AGGREGATE
Abstract
It's a significant step forward for the construction industry's product quality and efficiency that Self-Compacting Concrete (SCC) has been developed. When used on construction sites, SCC increases productivity while also improving working conditions, as well as the overall quality and aesthetics of the concrete. In SCC, the use of fibers helps to prevent fracture development by bridging any gaps in the concrete. When compared to ordinary concrete, they enhance energy absorption. In the fresh condition, Fiber Reinforced Self-Compacting Concrete (FRSCC) combines the advantages of SCC, but in the hardened state, it performs better than ordinary vibrated concrete owing to the inclusion of fibers. For various substitutions of Recycled Concrete Aggregate (RCA) in Natural Aggregate (NA), the current study presents the mechanical characteristics of Glass Fiber Reinforced M20 & M40 grade Self Compacting Concretes. Fiber addition to self-compacting recycled aggregate concrete increased split tensile strength by 10-15% while flexural strength improved by 10%. Concrete's modulus of elasticity has improved. They were also compared to the Indian Standard Code Provisions for Compressive Strength, Split, Flexure and Modulus of Elasticity.
