Concrete and cement-based materials must operate in increasingly aggressive aqueous environments, whichmay be either natural or industrial. These materials may suffer degradation in which ion addition and/or ion exchange reactions occur, leading to a breakdown of the matrix microstructure and consequent weakening. Sometimes this degradation can be extremely rapid and serious such as in acidic environments, while in other cases degradation occurs over long periods. Consequences of material failure are usually severe - adversely affecting the health and well-being of human communities and...

This proceedings volume consists of papers focusing on repairing, maintaining, rehabilitating, and retrofitting of existing infrastructures to extend their life and maximize economic return. Moreover, structural performance and material durability are discussed. Contributions fall under the following headings: (i) Concrete durability aspects, (ii) Condition assessment of concrete structures, (iii) Modern materials technology, (iv) Concrete repair, rehabilitation and retrofitting, (v) Performance and health monitoring, and (vi) Education, research and specifications. Major attention is paid...

The First International Conference on Concrete Repair, Rehabilitation and Retrofitting (ICCRRR 2005) was held in Cape Town, South Africa, from 21-23 November 2005. The conference was a collaborative venture by researchers from the South African Research Programme in Concrete Materials (based at the Universities of Cape Town and The Witwatersrand) and The Construction Materials Section at Leipzig University in Germany.

The conference has come at an opportune moment for concrete construction worldwide and sought to focus on an increasingly important aspect in modern infrastructure...

Ziel von Mark-Alexander Solf war die Identifizierung potenzieller Interaktionen sozialer, psychosozialer und anderer Personlichkeitsmerkmale mit definierten Krankheitsverarbeitungsstrategien, um die Individualitat des Herzkranken und dessen moglichen Profit von der dualen somato-psychischen Therapie zu unterstreichen. In der vorliegenden Studie hat er herzchirurgische Patienten zur Evaluation spezifischer psychischer Belastung und konsekutiver Krankheitsverarbeitung herangezogen. Der Herzpatient von heute ist aufgeklarter denn je. Sein personliches, biopsychosoziales Krankheitsverstandnis...
