Synopses & Reviews
The chemical decay of carbonate rock is a phenomenon of the twentieth century-the result of industrial pollutants reacting with both exposed and protected stone in monuments, buildings, and sites. This timely and authoritative work explains in depth the combined effects of weathering and pollution on carbonate stone, providing readers with effective tools to analyze structures and take the appropriate preservation steps. K. Lal Gauri, a major contributor to the emerging discipline of conservation technology, presents along with Jayanta K. Bandyopadhyay a broad overview of the field, combining knowledge gained through three decades of research as well as intimate involvement with the subject of the restoration of the Erechtheum, the Sphinx, and the Taj Mahal. Beginning with basic topics, the authors review rock properties that influence the weathering of stone, then move on to examine chemical and physical mechanisms occurring in polluted and natural environments, as well as biodeterioration. Lessons learned from the Great Sphinx are used to illustrate durability factors, rock age, and conservation methodologies, while treatments designed for both the Great Sphinx and the California Building are also clearly outlined. Finally, the book offers a unique, quantitative treatment on all aspects of weathering and conservation. The authors discuss mathematical modeling for predicting weathering under different conditions, showing how to evaluate chemical reaction rates and durability factors without subjecting rocks to actual engineering tests. Various modern-day modeling techniques are also discussed, including neural networks for correlating the large volumes of data generated by the chemical and physical measurements presented earlier in the book. Supplemented with 350 illustrations as well as a Web component to help in problem-solving when fundamental data is available, Carbonate Stone: Chemical Behavior, Durability, and Conservation is an indispensable guide for scientists, engineers, and professionals in the conservation field. Architects and engineers involved in the development of new structures and sites will also benefit from the quantitative approach to the information on carbonate rocks.

Synopsis
K. LAL GAURI, PhD, a Professor Emeritus at the University of Louisville, obtained a PhD in geology at the University of Bonn, Germany. After postdoctoral research at California Institute of Technology, he joined the University of Louisville in 1966, retiring in 1998. A permanent member of the committee of the International Congress on Deterioration and Preservation of Stone Objects, Dr. Gauri was president of its Fourth Congress, held in Louisville in 1982. He was the president of Sigma-Xi's Louisville chapter in 1974 and 1994. JAYANTA K. BANDYOPADHYAY, PhD, received his PhD in chemical engineering from Jadavpur University, India. As a research fellow at National Chemical Laboratory, he came to join Dr. Gauri as a research associate in 1993. He is presently a Research Engineer at United Catalysts, USA. He is a life member of the Indian Institute of Chemical Engineers and a member of the American Institute of Chemical Engineers and the American Chemical Society. Dr. Bandyopadhyay has contributed to the modeling techniques described in this book, in addition to writing the Web component of the book.
Synopsis
A Practical, Quantitative Approach to Conservation Methodology What can be done about the harmful effects of industrial pollutants on carbonate stone monuments, buildings, and sites? Here is an important guide to this phenomenon of the twentieth century. Written by two conservation technology experts with an intimate knowledge of the restoration of major world monuments, Carbonate Stone: Chemical Behavior, Durability, and Conservation covers:
* Properties of carbonate rocks affecting the weathering of stone
* Weathering mechanisms in polluted and natural environments, plus biodeterioration
* Mathematical modeling for reaction rates and durability factors
* The use of porosimetry in determining rock durability
* Conservation methodologies from the real world
* The theory of neural networks and their application to correlate large volumes of chemical and physical data
* Application of archaeology to geochronology
