Study On Engineering Properties Of Fly Ash-Based Geopolymer Concrete

The necessity to develop a new technology to produce energy-efficient and environmentally friendly concrete is evident, as it is known that cement production not only consumes large amounts of energy but also contributes substantially to greenhouse gas emissions. Inorganic materials containing mostly silicon (Si) and aluminium (Al) may be activated by alkaline solutions to form a geopolymer gel that binds the coarse and fine aggregates to form the concrete. The process needs significantly less energy and will not produce CO2 during production. This paper presents the results of a study on the engineering properties of geopolymer concrete utilising an industrial by-product, i.e. low calcium (class F) fly ash, as its base material.
