Abstract :

Concrete plays an important role in the construction industry and cement is the main ingredient of concrete which makes the binding in between fine aggregate and coarse aggregate. The production of cement results in emission of many greenhouse gases in atmosphere, which are responsi¬ble for global warming. Hence, the researchers are currently focused on use of waste material having cementitious properties, like GGBS (ground granulated blast furnace slag) Rice husk ash, which are easily available in market which can be added in cement concrete as partial replacement of cement, without compromising on its strength, stability and durability, which will 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. The GGBS is a waste product from the iron manufacturing industry, which may be used as partial replacement of cement in concrete due to its inherent cementing properties. This paper presents an experimental study of compressive strength of M20 grade of concrete. Jawergi sand from Bheema river is taken as fine aggregate which is black in color and was allowed to pass from 4.75mm of IS sieve. Cubes were cast with Ordinary Portland Cement, partially replaced by ground granulated blast furnace slag in different proportions varying 0% 15% and 30%. Curing period was taken as 3, 7 and 28 days. It is observed from the investigation that the strength of GGBS incorporated concrete is inversely proportional to the % of replacement of cement with ground granulated blast furnace slag
