Abstract
The use of Portland cement in concrete construction is under critical review due to high amount of carbon dioxide gas released to the atmosphere during the production of cement. In recent years, attempts to increase the utilization of fly ash (FA) to partially replace the use of Portland cement in concrete are gathering momentum. Most of this by-product material is currently dumped in landfills, creating a threat to the environment. Geopolymer concrete (GPC) is a ‘new’ material that does not need the presence of Portland cement as a binder. Instead, the source of materials such as fly ash, that are rich in Silicon (Si) and Aluminum (Al), are activated by alkaline liquids to produce the binder. Hence concrete with no Portland cement. This thesis reports the details of development of the process of making fly ash-based geopolymer concrete and its thermal properties. Due to the lack of knowledge of how it reacts with temperature, Geopolymer. In this study, evaluation of the thermal properties of FA-based (GPC) beams is reported in detail. The thermal properties are evaluated using the dry shrinkage strain and coefficient of thermal expansion (CTE).
