摘要

Infrastructure development plays key role in overall growth of any nation. The construction industry contributes approximately 8.99% to GDP of India (Qu et al. in J Build Eng 35, 2021 [1]). One of the highest quantities of material manufactured in infrastructure development is concrete. The total consumption of cement was projected to cross 370 million tonnes in 2022, which causing emission of carbon dioxide approximately about 37.4 billion tonnes in year 2023 (Statista in India: cement consumption volume, 2023 [2]). Significant amounts of natural resources that must be mined were used in the production process of cement. Substantial environmental costs have been incurred as a outcome of this quarrying, notably the destruction of biodiversity, the depletion of carbon sinks in nature, pollution of the air and noise, and disruption of streams and springs. Furthermore, even after quarries are eventually abandoned, these losses are unable to be restored. It seems best to come up with a green material possessing cement-like qualities to avoid the situations above. Despite the abundance of waste materials available to us, disposing of them is an issue. To reduce quarrying and CO2 emissions during the cement production process, such material can be utilized as replacement of cement or also cement less concrete. According to studies, geopolymer-based concrete (GPC) is one form of concrete that has been proven to lessen pollution by using zero cement, making it a more sustainable type of concrete. Concrete that recently had cement replaced with pozzolanic waste material—a waste product high in silica and aluminium—is known as geopolymer concrete. In this research, the same is accomplished by substituting cement by fly ash. A waste product which is available abundantly in power stations but also highly challenging to dispose of is fly ash. In this research paper, no cement concrete can be attained by using fly ash instead of cement. Fly ash is a waste material that is commonly found in thermoelectric power plant stations yet is highly challenging to dispose of.
