Study on silica fume-hybrid fiber composite modified alkali-activated slag concrete: mix ratio orthogonal experiment, crack propagation, and microstructure
ABSTRACT Alkali-activated materials (AAM), which are derived from aluminosilicate substances and activators, represent a sustainable and low-carbon alternative to ordinary Portland cement (OPC). The incorporation of fibers helps mitigate brittleness and enhance toughness. An orthogonal experimental approach was used to...
