This book presents a thorough review of the state-of-knowledge and recent innovations in the synthesis of pure and improved grades of fly ash zeolites (FAZ). Addressing improvements to conventional methods, it also showcases a novel technique for the synthesis of high cation exchangers from fly ash and detailed characterization techniques for the products obtained. In addition, it examines in detail various areas of specific applications of fly ash zeolites. Over the years, several methods such as hydrothermal, fusion prior to hydrothermal, microwave assisted hydrothermal and molten salt techniques for producing FAZ have been developed. However, one-step and two-step reactions between the fly ash and alkali usually generate alkaline wastes that may cause environmental contamination. In addition, the separation of FAZ from the partially activated fly ash (the impurities) remains a major concern for researchers and industrialists alike. In view of these challenges, this book presents a novel technique for three-step activation (TSA), which focuses on recycling the fly ash-NaOH-water reaction by-products until zeolitic residue is formed. The FAZ (the final residue after third step reactions) synthesized in this manner exhibits exceptionally high cation exchange capacity, specific surface area and pore area. This book offers a comprehensive compendium of reading material on fly ash and its recycled product, the zeolites. Students at both undergraduate and graduate levels, researchers, and practicing engineers will all find this book to be a valuable guide in their respective fields.

The rise of rapid and uncontrolled industrialization, its alarming levels of hazardous waste produced, and their negative contribution to the international environmental epidemic of global warming — in addition to the decrease in room to dispose of these wastes safely — have put the pressure for many engineers, researchers, and key decision-makers to find the answers to the constant tussle between progress and sustainability — and quickly.Environmental Geotechnology revisits existing concepts of geotechnical engineering critically, and brings them up to date with new knowledge and current affairs so as to better address and serve today's needs of the professionals. It points out the role and importance of the parameters and mechanisms that govern the interaction of contaminants with geomaterials (soil and rock mass), and also discusses their degradation in the long-run, and the consequences that follow.The book starts from a engineering philosophy that incorporates the influence of environmental effects (both manmade and natural) on geotechnical engineering practices. Its contents are based on geotechnical and environmental engineering studies pertaining to waste management, such as: the safe handling, transportation and disposal of waste, the estimation of waste leakage into the subsurface, its consequences, methods of containment, and the development of schemes to remediate contaminated land. It also proposes innovative strategies for waste management through the utilization of wastes based on a comprehensive characterization.Modelling techniques such as accelerated physical modelling using geotechnical centrifuge, finite-element or difference-based numerical modelling and physico-chemico-mineralogical modelling are discussed in this book to enable the study of the complex (and otherwise slow) process of contaminant-geomaterial interaction.

The book develops a practical understanding of the fundamental scientific principles and logic underlying the art of turf pitch preparation, measuring, analysing, and interpreting pitch surface behaviour. It’s an attempt to understand how the captains, players, coaches, curators, and groundsmen comprehend and analyse the cricket pitch behaviour (days before and during the matches) and whether the pitch behaviour can be standardised and quantified (through bench marking or forming a data-based management system (DBMS) of a pitch profile, pitch quality standards, a pitch behaviour analysis index (PBAI), or pitch behaviour forecasting (PBF) by examining or analysing its mineralogical, chemical, physical, or morphological compositions, weather variables, and different pitch preparation methods and techniques. Individual chapters in this book deal with clay mineralogy, the bench-marking of cricket pitch soils, pitch soil chemical properties, pitch soil water, pitch turf grass, pitch soilorganic matter, integrated rolling management, soil structure, and compressibility. This is an effort to decipher the impact of each and every major and minor component of pitch soil, which controls the pitch behaviour either in large or small magnitudes but acts as a critical factor in defining and shaping the pitch behaviour as a whole. Several real-life examples, pitch interviews, scenarios, and case studies as felt and observed by the curator( first author) during the preparation of various international, national, and board matches or during the construction and renovation of new wickets have been included in each and every relevant chapter so as to analyse, interpret, comprehend, and justify the theoretical science with the existing practises involved in pitch construction, preparation, or judging the complex nature of pitch behaviour. Based on findings through the DBMS, PBAI, and PQS of cricket pitch profiles, various innovative and simple methods of analysing, comprehending, and forecasting pitch behaviour have been devised that will enable one to judge and comprehend the complex pitch behaviour in simple ways.
