If we talk about today’s era, Concrete is the most important aspect in the present scenario in terms of construction. All the construction is being done with the help of this building material. Use of cement is rising on the peak from the last few decades due to the enormous demand for construction of megastructures all around the globe. In addition to that cement is the only material whose demand is increasing day by day in order to meet the needs of mankind. Subsequently, the price of cement is also increasing as its demand is increasing profoundly and also it available limited only. Manufacturing of cement results in the emission of CO2 and other gases which contribute to global warming and which further contribute to climate change and thus it is one of the most complicated material. Its use cannot be stopped but can be limited by using various materials. In order to dilute the use of cement, various alternatives and substitutes have been manufactured which is contributing to less pollution as compared to cement. Since cement cannot be fully replaced, it has been partially replaced with geopolymer using fly ash and GGBS.
