“…Therefore, increasing the silica fume reduces the voids between the slag grains and the gel, reducing water absorption. Silica fume in concrete densifies its microstructure due to small particle size and participates in chemical reactions, leading to the deposition of hardened products, which significantly reduces permeability [22].…”

“…The previously mentioned materials are used to reduce cement consumption and prevent environmental pollution induced by the construction industry [22]. Despite being produced without Portland cement, geopolymer concrete has displayed equal or even improved strength than ordinary Portland cement concrete [11,[23][24][25][26].…”

“…Although it may decrease compressive strength, partial replacement of MK by GGBFS up to 10% can improve early strength development in alkali-activated concrete mixes [14]. However, when combined with GGBFS, early strength type expanding agents and setting accelerators can greatly boost the compressive strength of early-stage concrete [15]. Overall, with the right mix design, additional additives, and curing techniques, the early concrete strength with GGBFS can be increased.…”
