Materials Science of Concrete Series – serie

This title is based on the workshop on Transport Properties & Concrete Quality, held at the campus of Arizona State University on October 10-12, 2005.During this meeting, scientific aspects of the relevant relationships between materials, mechanisms, processes, and service life were discussed.* Provides a useful resource for understanding the most valuable aspects of cement-based materials, with topics ranging from the current state of practice, to theory, simulation, and testing and specifications.* Logically organized and carefully selected articles give insight into the need to better integrate aspects of materials science, mechanics, modeling, and testing in developing tools of understanding the durability in cement-based materials.

This volume contains papers on phase composition and quantitative x-ray powder diffraction analysis of Portland cement and clinker; neutron diffraction and neutron scattering studies of cement; scanning probe microscopy: a new view of the mineral surface; the stereological and statistical properties of entrained air voids in concrete: a mathematical basis for air void system characterization; fresh concrete rheology: recent developments; early age behavior of cement-based materials; transport mechanisms and damage: current issues in permeation characteristics of concrete; the use of silica fume to control expansion due to alkali-aggregate reactivity in concrete: a review; delayed ettringite formation in concrete: recent developments and future directions; use of durability indexes to achieve durable cover concrete in reinforced concrete structures; and microfiller partial substitution for cement.

This book is a collection of papers from the symposium honoring Professor Sidney Diamond of the School of Civil Engineering, Purdue University, one of the leading scholars in the field of concrete science. The volume contains: Chemical and physical aspects of mechanisms of hydration of cements; development of concrete microstructure and mechanical properties; and various aspect of mechanisms of concrete deterioration, including alkali-silica reaction (ASR), freezing-thawing, and corrosion of reinforcement. Includes Dr. Diamond's paper, "Concrete Porosity Revisited."

This volume contains ten invited presentations on the topic of sulfate attack caused by external sulfate sources. The discussions concentrate on chemical and physical mechanistic aspects of the applicable sulfate-to-paste reactions and on the interrelationships between the internal (e.g., paste composition, pore solution, concrete matrix permeability) and external (e.g., composition of aggressive medium, temperataure and humidity, curing practices) variables.

This volume provides broad coverage of key issues related to the role of calcium hydroxide in cements and concrete. It contains critical topics such as the physicochemical role calcium hydroxide plays in hydration and deterioration of cementing properties as well as the implications of the presence of calcium hydroxide on the future of Portland cement, blended and specialty cements, and ecology of cement production.

This workshop brought together representatives from different areas of the cement and concrete community to discuss future trends and challenges in the field of concrete materials. Topics include developments and their potential for application, industry's view on what it needs from academia, academia's view on what it expects from industry and what they have to offer, technical advances and barriers to advancement, the role of governments, business issues, and ecological and societal barriers.

The world's infrastructure is largely built of concrete. With growing populations in the developing countries of the world, such as India, and with the decay of existing infrastructure in developed countries, such as the U.S., the need for new materials with improved properties has become as imperative now as ever. High-performance concrete composites that include fibers and particulate matter along with advanced chemical admixtures and complex ternary and even quaternary cement blends represent a growing proportion of the concrete being used and would possibly be the future norm. Topics covered from this conference include Defining High Performance and Today's State-of-the-Art; Fiber-Based Systems for High Performance; Next Generation Cement Blends for High Performance; and Tools for Modern and Next Generation High Performance Research.

This seventh volume of the Materials Science of Concrete series presents carefully selected state-of-the-art reviews on selected topics relevant to concrete and cement. This collection of new developments and information in the field of cement-based materials is a valuable resource for scientists, engineers, and academics interested in concrete.
