This book describes procedures and methodologies used predominantly to obtain a diagnosis of damaged concrete possibly caused by Alkali-Aggregate Reaction (AAR). It has two primary objectives, namely firstly to identify the presence of AAR reaction, and whether or not the reaction is the primary or contributory cause of damage in the concrete; and secondly, to establish its intensity (severity) in various members of a structure. It includes aspects such as field inspection of the structure, sampling, petrographic examination of core samples, and supplementary tests and analyses on cores, such as mechanical tests and chemical analysis. Evaluation of test data for prognosis, consequences and appraisal will be more fully set out in AAR-6.2.
Self-healing materials are man-made materials which have the built-in capability to repair damage. Failure in materials is often caused by the occurrence of small microcracks throughout the material. In self-healing materials phenomena are triggered to counteract these microcracks. These processes are ideally triggered by the occurrence of damage itself. Thus far, the self-healing capacity of cement-based materials has been considered as something "extra". This could be called passive self-healing, since it was not a designed feature of the material, but an inherent property of it. Centuries-old buildings have been said to have survived these centuries because of the inherent self-healing capacity of the binders used for cementing building blocks together. In this State-of-the-Art Report a closer look is taken at self-healing phenomena in cement-based materials. It is shown what options are available to design for this effect rather than have it occur as a "coincidental extra".
Alkali-Aggregate Reaction in Concrete: A World Review is unique in providing authoritative and up to date expert information on the causes and effects of Alkali-Aggregate Reaction (AAR) in concrete structures worldwide. In 1992 a first edition entitled The Alkali-Silica Reaction in Concrete, edited by Professor Narayan Swamy, was published in a first attempt to cover this concrete problem from a global perspective, but the coverage was incomplete. This completely new edition offers a fully updated and more universal coverage of the world situation concerning AAR and includes a wealth of new evidence and research information that has accumulated in the intervening years. Although there are va...

This RILEM AAR 1.2 Atlas is complementary to the petrographic method described in RILEM AAR 1.1. It is designed and intended to assist in the identification of alkali-reactive rock types in concrete aggregate by thin-section petrography. Additional issues include: • optical thin-section petrography conforming to RILEM AAR 1.1 is considered the prime assessment method for aggregate materials, being effective regarding cost and time. Unequivocal identification of minerals in very-fine grained rock types may however require use of supplementary methods. • the atlas adheres to internationally adopted schemes for rock classification and nomenclature, as recommended in AAR 1.1. Thus, rock type...

An investigation of Jewish identity politics and Jewish contemporary ideology using both popular culture and scholarly texts. Jewish identity is tied up with some of the most difficult and contentious issues of today. The purpose in this book is to open many of these issues up for discussion. Since Israel defines itself openly as the e~Jewish Statee(tm), we should ask what the notions of e(tm)Judaisme(tm), e~Jewishnesse(tm), e~Jewish culturee(tm) and e~Jewish ideologye(tm) stand for. Gilad examines the tribal aspects embedded in Jewish secular discourse, both Zionist and anti Zionist; the e~holocaust religione(tm); the meaning of e~historye(tm) and e~timee(tm) within the Jewish political discourse; the anti-Gentile ideologies entangled within different forms of secular Jewish political discourse and even within the Jewish left. He questions what it is that leads Diaspora Jews to identify themselves with Israel and affiliate with its politics. The devastating state of our world affairs raises an immediate demand for a conceptual shift in our intellectual and philosophical attitude towards politics, identity politics and history.
"In Knowing Tomorrow, well known futures researchers from around the world [e.g., Italy, the U.K., the U.S.A, the Netherlands, Taiwan, and Australia) discuss how the future is being dealt with in different sciences. They describe how scientists have incorporated the future in their theories, thereby often taking a historical perspective. The findings of this book can offer strong support to the scientific foundations of futures research and thus improve futures research as a scientific discipline."--BOOK JACKET.
