This book presents the work of the RILEM TC 294-MPA and serves as a comprehensive and authoritative review of the latest advancements in alkali-activated materials (AAMs). It covers the chemistry and mix design of AAMs, including conventional and novel precursors, as well as activators. The mechanical properties of fresh and hardened AAMs, along with bond behaviors in reinforced systems (rebars and fibers), are examined in detail. Key volume stability challenges like autogenous shrinkage, drying shrinkage, creep, and cracking potential are thoroughly addressed. Practical applications, standards, and norms for AAM production are also included, bridging the gap between theory and practice. This state-of-the-art resource is invaluable for researchers, engineers, and policymakers seeking to advance sustainable construction materials. It highlights cutting-edge developments, from innovative materials to standards adoption, ensuring relevance for both academia and industry. The book empowers professionals to tackle performance challenges while promoting AAMs as eco-friendly alternatives.
