摘要：With rapid increases in Industrialization the need for efficient disposal of industrial effluents has alsosurged. One of the biggest industries is the construction industry, a large amount of waste products are releasedduring production of certain construction materials such as paints, cement, metals etc. In this paper we focus on theuse GGBFS (ground granulated blast furnace slag, a by-product of steel and iron production) as an admixture incement in order to reduce cement production and effective disposal of industrial waste.The waste that have to be disposed can be kept to use in some manner, among the industrial waste possessingcementations nature can be replaced as binder matter in concrete to apart . A large volume of production of cementleads to emission of many harm full gases like greenhouse gases in atmosphere, which are tends for global warming.Hence, the researchers are currently focused on waste material having cementing properties, which can be done bypartial replacement of cement which would further lead to reduction in cement production and therefore lesseremission of greenhouse gases, to sustain-able management of the industrial waste, Some of the Pozzolanic materialslike flay ash, Silica fume, Rice Husk ash, Metakoline, Ground Granulated Blast Furnaces Slag (GGBS) are used ascementations materials. Among them the Ground Granulated Blast Furnaces Slag,(GGBS) which is the wastefrom, of iron manufacturing industry, which may be used as substitute of cement in concrete due to its inherentcementing properties.To better understand the influences of Ground granulated blast furnace slag (GGBFS) on the properties of concrete,the compressive strength development with the addition of GGBFS of 45μ m were investigated. GGBFS is obtainedby quenching molten iron slag (a by-product of steel and iron-production) from a blast furnace in steam or water toproduce a glassy, granular product that is then dried and ground into a fine powder. This material hascementitious properties and therefore it can be used as a partial replacement of the cement otherwise it would havebeen a disposal. Recycling of slag will inevitably become an important measure for the environment protection andtherefore will be of great significance. The present paper focuses on investigating characteristics of M25 concretewith partial replacement of cement with GGBFS. The detailed experimental investigation was done to study theeffect of using GGBFS (Micro- GGBFS) in various proportions starting from 5% to 20% cement concrete. Thecompressive strength test on hardened cement concrete cube of size 150mm x 150mm x 150mm at 28 days of curingwere carried out. The work presented in this report reveals the effect on the strength of cementitious composites atdifferent proportions of GGBFS. From this study it is found that by the partial replacement of cement with GGBFShelped in improving the strength of the concrete substantially compared to normal mix concrete.This usage of GGBS serves as replacement to already depleting conventional building materials and the recent yearsand also as being a by-product it serves as an Eco Friendly way of utilizing the product without dumping it onground.However the above research was limited to the use of GGBFS in M25 concrete. The scope of the research is furtherbroadened by understanding the effects and feasibility of using GGBFS as partial replacement material in highergrade, M40 concrete. Efficient disposal of a waste product can only be justified if it is universally viable therefore, ifGGBFS can be used flexibly in construction along with varying concrete mixes only then we can achieve itspurposeful use in Civil Engineering. Prestressed structures are made with high grade concrete such as M40concrete therefore, Experimental studies are conducted on M40 grade concrete prepared with 53
