This symposium proceedings investigates the critical role of admixtures in enhancing the properties of concrete. Edited by E. Vazques, this collection presents research from an international RILEM Symposium, focusing on the scientific principles and practical applications of various concrete admixtures. The work details how these additives modify concrete's fresh and hardened states, addressing challenges in durability, workability, and strength.

This collection of papers from the RILEM Symposium serves as a technical reference for professionals and researchers in concrete technology. The proceedings offer detailed insights into the mechanisms by which admixtures improve concrete properties, covering both established and emerging materials. The focus is on scientific understanding and practical application, making it a valuable resource for advancing concrete performance in construction.
