Cement-based concrete has excellent properties as a construction material, and the raw materials of cement—rocks, and limestone and clay—are bountiful. Yet its production generates high quantities of CO2, making it a potentially unsustainable material. However, there are no alternatives to concrete and steel as basic methods for development of socioeconomic infrastructure at this time. Highlighting sustainability issues in the construction industry, The Sustainable Use of Concrete presents guidelines on how to move toward sustainable concrete construction.
The book begins by clarifying the historic background and meaning of sustainability, after which it outlines areas that need to be considered in connection with sustainability in the concrete and construction field. It examines environmental, social and cultural, and economic aspects, then considers an evaluation system of sustainability. The authors include various tools and ISO standards, and then explore technologies for sustainability, with case studies and examples that promote understanding of current technologies.
Although the construction sector, in the broadest sense, has come to recognize that infrastructure development over the past two centuries has been unsustainable, it has been slow to adjust. Comprehensive information and relevant practical guidance are very scarce. This book lays out a roadmap for creating a human-friendly and safe environment with low environmental burden.

A general solution to vibrations of beams on variable Winkler elastic foundation is presented. The exact solution of the dynamic response of the beam is obtained by considering the reaction force of the foundation on the beam as the external force acting on the beam, which is an integral equation including the displacement of the beam. The four unknown constants in the solution are decided by the boundary conditions of the beam. The integrals in the solution are approximately and numerically calculated by means of the trapezoidal rule. By letting the right-hand side of the solution equal its left-hand side only at those discrete nodes of the quadrature, the frequency equation is obtained which is described by a determinant whose order is equal to the number of the discrete nodes. The mode shape functions are represented by a series of unified analytical functions. The analysis and programing are very simple. It is possible to find the natural frequencies and mode shapes of vibrations by using a small number of the discrete nodes in the trapezoidal quadrature and it is concluded that the use of the method yields better convergence at lower computation costs. Finally, several examples are given for simply supported beams on variable Winkler elastic foundation.

Groundwater Lowering in Construction: A Practical Guide to Dewatering, Second Edition
Author: Pat M. Cashman and Martin Preene | Size: 87.20 MB | Format:PDF | Quality:Original preprint | Publisher: CRC Press | Year: 2012 | pages: 645 | ISBN: 9780415668378
Linking theory and application in a way that is clear and understandable, Groundwater Lowering in Construction: A Practical Guide to Dewatering, Second Edition uses the authors’ extensive engineering experience to offer practical guidance on the planning, design, and implementation of groundwater control systems under real conditions.
Discover engineering methods that can help you improve working conditions, increase project viability, and reduce excavation costs.
In the decade since publication of this book’s first edition, groundwater lowering and dewatering activities have been increasingly integrated into the wider ground engineering schemes on major excavations to help provide stable and workable conditions for construction below groundwater level. Consequently, many engineering ventures now require a more in-depth assessment of potential environmental impacts of dewatering and groundwater control, and this book details the latest best practices to evaluate and address them.
Includes New Chapters Covering:
- Cutoff methods used for groundwater exclusion
- Issues associated with permanent or long-term groundwater control systems
- Groundwater control technologies used on contaminated sites
- Methods needed to understand, predict, and mitigate potential environmental impacts of groundwater control works
Updated to reflect the crucial technological and application advances shaping construction processes, this book contains valuable direction that can give you a true competitive advantage in the planning and execution of temporary and permanent dewatering works. The authors cover cutting-edge methods and key subjects, such as the history of dewatering, working on contaminated sites, site investigation techniques, and operation and maintenance issues, including health, safety, and legal aspects. Written for practising engineers and geologists as well as postgraduate engineering students, this updated manual on design and practice provides numerous case histories and extensive references to enhance understanding.

Author: Abdul Razzak Rumane, Director, Construction Quality Management, Dar Alkuwait Alkhaleejia for Consultation and Training, Kuwait | Size: 3.89 MB | Format:PDF | Quality:Original preprint | Publisher: CRC Press | Year: 2013 | pages: 413 | ISBN: 9781466552142
Dealing with such a multi-layered and fungible intangible as quality during the design and construction process is difficult for all parties involved. To the architect, quality means an appealing and enduring design, but to the builder, it means understandable documents that, when acted upon, lead to an enduring, well-made structure. To the owner, it is the end result: a building that is not only fit for the purpose, but a positive addition to its surroundings. Reconciling these seemingly contrasting priorities requires processes that are embedded not just at the project level, but within the entire enterprise with designer, builder, and owner committed to integrating quality into all their business processes.
Quality Tools for Managing Construction Projects not only details the importance of developing a comprehensive management system, but provides the tools and techniques required to do so. The book examines the usage and applications of tools and techniques in different phases of a construction project, focusing on plan quality, quality assurance, and quality control. Following the construction cycle, Dr. Rumane delineates the quality tools and their application, ending with the implementation of quality systems throughout the entire design and construction cycle.
The book demonstrates how these tools can help in planning, executing, monitoring, and controlling a project—evolving project management into a system that ensures project deliverables consistently meet the defined scope on schedule and within budget. The author’s systems perspective recognizes and supports the ideal collaborative approach that modern design and construction projects need. Dr. Rumane then demonstrates that successful quality management is more than a series of handoffs between teams who’ve completed tasks.
