Recycling and utilization assessment of waste fired clay bricks (Grog) with granulated blast-furnace slag for geopolymer production

In the present study, the alkali-activation process potential of the industrial by-product called waste fired clay bricks (Grog) as well as the effects of the addition of another industrial by-product known as granulated blast-furnace slag (S) on the properties of the final products has been studied. Granulated blast-furnace slag has been employed as 20%, 40%, 60% and 80% replacement of waste fired clay bricks (Grog) in the production of geopolymers. At the same time, the effects of curing time on the properties of geopolymers were investigated. The study proved a successful method for the feasibility of recycling and valorization process of two industrial by-products and converts them into valuable geopolymer products. These potential recycling processes can generate significant benefits for environmental sector and many economic impacts to the construction materials sector by using it as alternative raw material resources for the production of the geopolymer.
