Reviewing the influence of GGBFS on concrete properties

Abstract

Urbanization and industrialization are at its peak in present because of the advancements and breakthrough coming in every field across the world. As such advancements come with a cost, as of now it’s our environment suffering heavily. Be it the toxic gases released into the atmosphere or the solid waste dumped into the land, cause distress to our environment disrupting the balance of nature. Every material that is manufactured leaves a residual behind in the form of waste product that requires proper treatment and disposal for reducing its unwanted repercussion on environment. Such being the case with extraction of iron from its ore or in the steel making process that leave behind a solid waste in the form of slag, whose properties wholly depend upon the process of cooling adopted. One of its form i.e., Ground Granulated Blast furnace Slag (GGBFS) possess properties similar to that of cement thus is a probable replacement for it. Steel industry is one of the top growing industries in construction thus enormous production of steel leads to abundant slag generation. Since it’s a by-product, replacing the cement in concrete would be economical and possible means for slag disposal.This paper frames a detailed report on GGBFS as cement replacement from published work regarding the effect of GGBFS on different properties of concrete along with its production. In this paper production of GGBFS, the impact that GGBFS has on concrete properties like hydration, setting time, workability, compressive strength, flexural strength, micro-structure, modulus of elasticity and durability is canvased.
