Concrete Demands

Between the 1950s and 1970s, Black Power coalesced as activists advocated a more oppositional approach to fighting racial oppression, emphasizing racial pride, asserting black political, cultural, and economic autonomy, and challenging white power. In Concrete Demands, Rhonda Y. Williams provides a rich, deeply researched history that sheds new light on this important social and political movement, and shows that the era of expansive Black Power politics that emerged in the 1960s had long roots and diverse trajectories within the 20th century. Looking at the struggle from the grassroots level, Williams highlights the role of ordinary people as well as more famous historical actors, and demonstrates that women activists were central to Black Power. Vivid and highly readable, Concrete Demands is a perfect introduction to Black Power in the twentieth century for anyone interested in the history of black liberation movements.

Optimization methodologies are fundamental instruments to tackle the complexity of today's engineering processes. Engineering Optimization 2014 is dedicated to optimization methods in engineering, and contains the papers presented at the 4th International Conference on Engineering Optimization (ENGOPT2014, Lisbon, Portugal, 8-11 September 2014). The book will be of interest to engineers, applied mathematicians, and computer scientists working on research, development and practical applications of optimization methods in engineering.

This broad-based, introductory reference provides excellent discussions regarding the hydration of Portland cement, durability problems in concrete, mechanisms of concrete deterioration, and interaction of polymers in concrete. It also covers properties of concrete with added polymers and practical applications of polymers in concrete. The historic background of polymers in building materials is examined, and a comprehensive comparison of natural vs. synthetic polymers is provided and conveniently summarized in a tabular format.

This state-of-the-art volume covers the latest and future trends in measuring, monitoring and modeling the properties of cement based materials. The book contains 94 papers and presents the latest research work of renowned experts. It acts as a survey of the most up-to-date research in the field.

3D Concrete Printing Technology provides valuable insights into the new manufacturing techniques and technologies needed to produce concrete materials. In this book, the editors explain the concrete printing process for mix design and the fresh properties for the high-performance printing of concrete, along with commentary regarding their extrudability, workability and buildability. This is followed by a discussion of three large-scale 3D printings of ultra-high performance concretes, including their processing setup, computational design, printing process and materials characterization. Properties of 3D-printed fiber-reinforced Portland cement paste and its flexural and compressive strength, density and porosity and the 3D-printing of hierarchical materials is also covered. Explores the factors influencing the mechanical properties of 3D printed products out of magnesium potassium phosphate cement material Includes methods for developing Concrete Polymer Building Components for 3D Printing Provides methods for formulating geopolymers for 3D printing for construction applications

This book presents new information on concrete properties and production in the light of the widespread use of ready mixed concrete and new concreting materials. This book forms the Proceedings of the RILEM Colloquium held in Hanover, West Germany in October 1990. Papers from 18 countries in Europe, North America and the Far East are included.
