This has translated into the conventional view that there was an inherent problem in the natural cement concrete used to build these fortifications. However, for reasons of economy, the Corps of Engineers were prevented from using portland cement, until advances in domestic manufacturing permitted a reduction in costs. Through historical and archival research, as well as the petrographic analysis of concrete samples, a more detailed assessment of the concrete used at Fort Totten was conducted. Using polarized light microscopy an analysis was conducted on the binder, the aggregates, the gradation, the water/cement ratio, and any deterioration in order to evaluate changes in the concrete mix design over time. These observations were then related to a conditions survey of the concrete structures at Fort Totten, to assess the performance of the concrete used to build these historic structures. Laboratory work for this thesis was conducted at Columbia University GSAPP's Historic Preservation Conservation Laboratory and at Highbridge Materials Consulting, Inc.

"This unique, new resource provides historical and technical foundations in the original uses of natural cement, and disseminates current information on contemporary practices and results of recent research. Over the past 20 years, there has been a growing revival in the use of traditional materials for the restoration and maintenance of historic buildings and structures. The pivotal role of natural cement in 19th and early 20th Century construction has been rediscovered, but new research is required to update and redefine our understanding of traditional materials and performance expectations in terms of modern standards and testing protocols."--Publisher's website.

Concrete is by far the most common building material— accounting for twice the volume of all other such materials combined. With such a huge global economic impact, the industry has a correspondingly considerable responsibility to use it sustainably. Written by experts who pioneered research into environmental issues and concrete, Concrete and Sustainability examines the sustainability issues of the world’s main construction material and proposes attainable solutions. It provides a complete overview of the topic and tackles the complexity of the challenges from different angles. This book offers new data regarding the social and economic importance of concrete and proposes a discussion centered on a holistic approach in terms of resource availability, technical viability, economic feasibility, and environmental compatibility. The authors attribute a growing worldwide concern and understanding of sustainability issues, and an increased focus on climate change as the catalyst in this process. Instead of offering detailed technical advice or recommendations on sustainable issues, they provide examples showcasing sustainability efforts taking place in the concrete environment worldwide. The book includes examples and ideas for solutions from a large number of countries from across the globe. It presents a holistic and more complete overview of the emission and absorption topic, takes a look at the challenges from a combined old and new world viewing platform and offers an exploration of issues from a social and economic perspective. Concrete and Sustainability details the various rules and regulations that the industry is facing, discusses the various environmental challenges, and explores its impact. As emission, absorptions, and recycling have been the most central elements of discussion in the cement and concrete environment so far, these topics each receive their own chapters. This book also discusses other issues of concern within the various platforms in the industry, as well as future developments, and provides a comprehensive reference list.
