Abstract:In the present world, the technology is changing at a high pace, concrete is one among them and has turned into a key piece of our lives. With each passing day, the use of cement is expanding at a high rate. One of the core constituents of concrete is Portland cement. With the increase in utilization of concrete, the manufacturing and consumption of cement have increased drastically. Despite the fact that bond has uncommon restricting properties and is extremely apt for use in concrete, the assembling of concrete outcomes in the discharge of a lot of CO2. Due to this, researchers have commenced finding alternatives to cement that are economical as well as environment-friendly. Fly ash and Ground granulated blast furnace slag are industrial by-products which postulate admirable binding properties to concrete and accommodate as a supersession of cement. These alternatives are generally termed as Supplementary cementations materials (SCMs). The utilization of these materials not only avails in reducing the consumption of cement but withal accommodates as an efficient method for their safe disposal. This paper analyses the effect of utilizing these materials that can be utilized in concrete as partial replacement of cement. The literature review of sundry researchers reveals that a single alternative cannot provide all the benefits that cement does. Rather, a suitable combination of these products can be incorporated in concrete to provide properties better than that of Portland cement concrete. And research in the field of AAS and fly ash concrete states that this new material is high potential to replace an alternative to Portland cement. This article presents an in-depth review of alkali-activated slag and flies ash-based concrete. The paper covers composition, mixing and curing process, benefits, limitations, and applications of AAS and fly ash-based concrete..
