Conference Name :
The production of cement results in emission of many green house gases in atmosphere , which are responsible for global warming. Hence the results are currently focussed on use of waste material having cementing properties , which can be added in cement concrete as partial replacement of cement , without compromising on its strength and durability , which will result in decrease of cement production thus reduction in emission in green house gases , in addition to sustainable management of the waste. The GGBS is a waste product from the iron manufacturing industry , which may be used as a replacement of cement in concrete due to its inherent cementing properties. This paper presents an experimental study of compressive and flexural strength of concrete prepared with ordinary Portland cement , partially replaced by GGBS in different proportions varying from 0%,15%,30% & 45% in M30 grade of concrete. It is observed from the investigation that the strength of concrete is inversely proportional to the % of replacement of cement with GGBS. And in addition crystalline waterproofing agent is added to the ratio of 125ml for 50kg cement bag , it gives better strength.
