Abstract :

The study of concrete in civil engineering is increasing day by day and the amount of cement required for the construction of concrete is also increasing by which the production of cement results in emission and pollutes the environment. Therefore by researches, it has been concluded that the replacement of cement can be done partially with waste products like GGBSwhich is by product of molten iron which have inherent Cementitious property, It gives compressive strength of concrete without compromising on its strength, stability and durability, which result in decrease of cement production and reduces global warming thus reduction in emission in greenhouse gases, in addition to sustain¬able management of the waste. This paper presents an experimental study of compressive strength of M30 grade of concrete prepared with Ordinary Portland Cement, partially replaced by ground granulated blast furnace slag in different proportions varying 0%, 7.5%, 22.5%, and 37.5%. curing period of concrete is taken as 3,7, and 28 days and compressive strength has been tested The curing period required for GGBS admixtures added in concrete should require more compare to standard concrete. It is observed from investigation that the degree of workability is normal and the strength of concrete decreases as the percentage of GGBS increases.
