Characterization and utilization of alkali-activated concrete for sustainable infrastructures
… locally available fly ashes (FAs) to synthesize alkali-activated concrete (AAC) for different structural and repair applications. Using AAC made of 100% FA reduces global CO2 emissions, saves energy, and decreases raw material consumption during the production process of ordinary Portland cement. …

The performance of a blended PFA/GGBS alkali-activated concrete using a silica fume-based activator
… undertaken into ‘’’cement-free’’ alternative concrete has emerged in the academic and commercial space also known as alkali-activated concrete, bringing CO<sub>2</sub> reductions of up to 85%. AAC has been elevated as a viable solution detrimental to the ‘sustainable toolkit’ for low-carbon …

Mix design, fresh and hardened properties and microstructural characterisation of alkali-activated concrete based on PFA/GGBS blends
Alkali-activated concrete (AAC) has recently emerged as a potential candidate to replace the conventional Portland cement concrete (PCC) in several applications due to its low CO2 footprint and promising mechanical properties. However, the robustness and the good reputation PCC has gained over the …

Durability of alkali-activated calcined clay - GGBFS concrete against carbonation and chloride diffusion
… binders, called geopolymer, is obtained from the alkaline activation of raw materials rich in SiO₂ and Al₂O₃, which can be derived from by-products or industrial residues. Calcined clay has emerged as a potential candidate as a precursor for this type of material. Large amounts of suitable clays …
