Overview

This book presents the work of the RILEM TC 258-AAA WP3, and serves as a comprehensive review of the role of alkalis in concrete in relation with the alkali-silica reaction. Chapter 1 investigates different aspects of the reaction related with the prevention, the characterization and development with the time of the ASR and the factors of influence. Chapter 2 is an in-depth analysis of the internal alkalis in the concrete components, while the Chapter 3 is related with the alkalis of the external alkalis. Chapter 4 provides valuable information about the standardization and regulations to prevent and to taking actions to minimizing the degradation due to the ASR. Finally, the Annex examines different structures, mainly pavements with flat shape and low volume of concrete, and dams with a very big volume of massive concrete and different tensional areas.

Author Information

Esperanza Menéndez Méndez (deceased), PhD from Polytechnic University of Madrid, was Researcher at IETcc-CSIC (Instituto Eduardo Torroja de Ciencias de Construcción - Spanish National Research Council), where she served as Head of the Physic-Chemistry Testing Unit. She was a leading expert in several techniques of characterization of construction materials, pathology and durability of concrete structures, buildings and cultural heritage. António Santos Silva, PhD in Civil Engineering from Minho University in Portugal, is Senior Researcher at the Materials Department of LNEC (Laboratório Nacional de Engenharia Civil - National Laboratory for Civil Enginnering. His research interests focus on building materials, including its characterization and performance, mitigation of internal expansive reactions in cement-based materials, and compatible materials for conservation of historical heritage.
