Abstract

The construction industry must ensure a new occupant experience that is connected, safe, and comfortable. Due to its versatility, concrete is the most frequently used building material worldwide. Cement is an essential ingredient of concrete, but it is not considered environmentally friendly. The production of Portland cement consumes a considerable amount of energy and emits a significant amount of carbon dioxide. By creating and utilizing alternative materials, like geopolymers, construction may become much more sustainable. Cement production has a significant environmental impact, which must be reduced by developing new binder types. With the use of various industrial byproducts, the workability, impacts of temperature change, usage of admixtures, use of fibers, and effects of the water-binder ratio of geopolymer concrete are all investigated. It indicates that the regulated geopolymer concrete mix's compressive strength is inferior to that of geopolymer concrete with additional hooked-end steel fibers. As a recent innovation in concrete, Geopolymer is a substance in which fly ash, which is activated by an alkaline solution to act as a binder, completely replaces cement. Geopolymer concrete was analyzed with different ratios of activators for strength analysis. To select the correct ingredients for geopolymer concrete to achieve the desired strength at the desired workability, the grading of geopolymer concrete following the Indian Standard Code has been the subject of experimental effort. Assessing the amount and fineness of fly ash, the amount of water, or the amount of alkaline liquid is a step in the mix design process, along with the W/C ratio, fine aggregate quality, fine aggregate proportion to total aggregate, and superplasticizer content. Premixed geopolymer concrete's compressive strength, shear strength, flexural strength, and bonding strength will be evaluated after the materials' internal reactivity has been verified.
