Geopolymer Concrete: Advancements in Performance and Sustainability, Elsevier, ss.99-125, 2026
Bricks, which have been used as a durable building material for many years to build buildings in the civil engineering sector, can be joined together with adhesives or by interlocking. The modern version of interlocking parquet blocks was produced in the late 1940s to replace burnt bricks and was introduced as an alternative to brick blocks. Although these blocks attract much attention with their reuse potential and esthetic appearance, the demand for brick cement, widely used as construction walls, cladding, garden walls, and flooring in building constructions, significantly increases, causing energy-intensive processes and significant greenhouse gas emissions. Many organizations worldwide are taking initiatives to reduce their raw material consumption from the cement and aggregate industries to protect environmental quality and ensure sustainability. This situation has led to the use of new materials and the development of advanced production techniques in contemporary concrete technology. In this context, one of the studies on the production of binders without using Portland cement is the activation of by-products with different alkalis. In this context, in the studies carried out so far, metakaolin, fly ash, and slag by using NaOH or KOH, Na2SiO3, or K2SiO3 in the activation and double or triple combinations of these materials with by-products alkali-activated binders, in other words, geopolymers, are designed. Accordingly, this chapter deals with the sustainability of GBs in general and focuses specifically on current studies on material, method, and mixture design at the production stage.
