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 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 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.
