Book Description
This report presents the results of a research program examining the potential benefits of requiring minimum and maximum mortar contents for 37.5 mm (1-1/2 in.) nominal maximum size aggregate (NMSA) mass concrete and minimum and maximum paste-mortar ratios for 37.5 mm (1-1/2 in.) NMSA mass concrete. The purpose of the research program was to supplement existing guidance on proportioning mass concrete mixtures. Two 37.5 mm (1-1/2-in.) nominal maximum size (NMS) coarse aggregates were used. One was a crushed material consisting primarily of blocky particles. The other was a crushed material having more flat and elongated particles. All mixtures contained natural fine aggregate. The results indicate that a recommended minimum and maximum mortar content could be a useful guide to aid in proportioning workable mass concrete mixtures containing 37.5 mm (1-1/2-in.) NMS coarse aggregate. An approximate minimum and maximum mortar content was identified for mixtures containing favorably shaped coarse aggregate particles (primarily blocky with minimal flat and elongated) and for mixtures containing less favorably shaped coarse aggregate particles (higher percentage of flat and elongated). The paste-mortar ratio appears to be less useful. Recommendations are made to consider supplementing existing guidance on proportioning 37.5-mm (1-1/2-in.) NMSA mass concrete mixtures with minimum and maximum mortar contents.

Book Description
This book provides a State of the Art Report (STAR) produced by RILEM Technical Committee 254-CMS ‘Thermal Cracking of Mas-sive Concrete Structures’. Several recent developments related to the old problem of understanding/predicting stresses originated from the evolution of the hydration of concrete are at the origin of the creation this technical committee. Having identified a lack in the organization of up-to-date scientific and technological knowledge about cracking induced by hydration heat effects, this STAR aims to provide both practitioners and scientists with a deep integrated overview of consolidated knowledge, together with recent developments on this subject.

Book Description
Concrete Solutions contains the contributions from some 30 countries to Concrete Solutions, the 6th International Conference on Concrete Repair (Thessaloniki, Greece, 20-23 June 2016). Strengthening and retrofitting are major themes in this volume, with NDT and electrochemical repair following closely, discussing the latest advances and technologies in concrete repair. The book brings together some interesting and challenging theoretical approaches and questions if we really understand and approach such topics as corrosion monitoring correctly. Concrete Solutions is an essential reference work for those working in the concrete repair field, from engineers to architects and from students to clients. The Concrete Solutions Series of international conferences on concrete repair began in 2003 with a conference held in St. Malo, France in association with INSA Rennes. Subsequent conferences have seen the Series partnering with the University of Padua (Italy) in 2009, with TU Dresden (Germany) in 2011 and with Queen’s University Belfast (Northern Ireland) in 2014. In 2016 Thessaloniki (Greece) hosted the conference, partnering with both Aristotle University of Thessaloniki (AUTH) and Democritus University of Thrace (DUTH). The next conference in the series will be held in 2019 in Istanbul.
