Drying shrinkage of alkali-activated concrete -State-of-the-art: a research study into the mechanisms, the influencing factors, and mitigation strategies of drying shrinkage of alkali-activated concrete

Alkali-activated concrete (AAC) has emerged as an environmentally friendly alternative to conventional concrete, as It is a cement-free concrete made by activating precursors (mainly low-cost, low-CO2 industrial by-products) with alkalis. AAC has demonstrated some remarkable mechanical properties and long-term performance (e.g., high strength,...
