HIGH ELECTRICAL RESISTANCE CREAMICSPond and fly ash waste materials generated by thermal power stations pollute the environment; this book demonstrates how the utilization of these materials minimizes environmental pollution and conserves land for cultivation.This book highlights the preparation of ceramics using pond/fly ash. Since the mullite phase formed by heat treatment improves the properties of ceramics, current investigations will perhaps be the first attempt to develop ceramics using pond ash. The properties of components made with these developed ceramics are found to be comparable to those made with porcelain.The extensively reviewed chapters of this book illustrate the current status of research on these materials. At the end of each of the 10 chapters, conclusions are drawn which will benefit researchers working in this area. Subjects discussed include:* The fundamentals of thermal power plant wastes;* Different production methods of ceramics and various characterization techniques;* The preparation of ceramics from fly ash and fly ash/kaolin composite;* The production of ceramics using pond ash;* The preparation and characterization of geopolymer from pond ash and the preparation of pond ash composite;* Production of ceramic matrix composite (CMC) using pond ash and pyrophyllite;* The preparation of ceramics using pond ash and k-feldspar mixture.AudienceThe book will be used by civil engineers in the construction and ceramic industries as well as the industrial waste sector. Researchers in materials science, structural, civil and electrical engineering, environmental science, and ceramic engineering, will also have interest. Industries that have an interest include construction, electrical, and ceramic industries as well as pollution and waste sectors.

DEVELOPMENT OF GEOPOLYMER FROM POND ASH-THERMAL POWERPLANT WASTEExplains how geopolymer technologies using industrial waste obtained from thermal power plants become cementitious materials in construction sectors for civil engineers.Utilization of waste materials has become a global challenge since they endanger our environment. In this book, the authors demonstrate how to utilize fly ash/pond ash (waste materials from thermal power plants) to produce a novel material called 'Geopolymer' (GP). Red mud, slags, etc., are mixed with fly ash to produce GP with enhanced strength. As shown in a few European countries, GP can replace cement, and some permanent structures constructed with GP are now appearing in a few advanced countries. GP, and geopolymer concrete, is considered suitable for the construction of roads, buildings, etc., and will eventually, fully or partially, replace cement.The book highlights the mechanism of the formation of GP from pond ash. Properties of structures made with GP concrete are found to be comparable to those made with cement concrete. Systematic investigations are presented to understand the chemistry of GP formation with pond ash materials. Performances of these materials above ambient temperature, as well as with different environmental conditions, are also evaluated.AudienceThe book will be used by civil engineers in the construction and ceramic industries, as well as the industrial waste sector. Researchers in materials science, structural and civil engineering, environmental science, and ceramic engineering, will also benefit. Additionally, the book is suitable for graduate courses in civil engineering.
