Book Description
Phytomanagement of Fly Ash brings together the recent and established knowledge of different aspects of fly ash management, providing a cutting-edge synthesis of scientific and experiential knowledge on contaminated site restoration. Phytomanagement of Fly Ash provides readers with ecologically friendly and cost-effective solutions to decontaminate fly ash polluted sites, along with potential opportunities in phytoremediation that also yield biodiesel, aromatic oil, bio-fortified products and pulp-paper biomass. The book also focuses on novel topics, such as afforestation on fly ash catena, adaptive management, potential sink for carbon sequestration, and ecosystem goods and services. This book is a useful reference for environmental professionals in the coal industry, ecological planners and managers, students, practitioners and policymakers involved in phytoremediation. - Provides a holistic approach to fly ash, covering the ecological, economic and social issues related to its management - Addresses the multiple industrial uses of fly ash - Includes strategies to mitigate costs related to fly ash dump restoration

Book Description
Soil stabilization is the process whereby soils and related materials are made stronger and more durable by mixing with a stabilizing agent. These techniques are used for road construction in most parts of the world, although the circumstances and reasons for resorting to stabilization vary considerably.

Book Description
The use of renewable bioenergy is increasing, and so is the production of associated wastes: biomass ashes. This book presents eleven chapters on the options for recycling such biomass ashes, ranging from their use as fertilizer in agriculture and forestry to their application as a supplement for the production of cement-based materials or bricks. The book also examines the pros and cons for each of the different uses of biomass ashes.

Book Description
Previous Iowa DOT sponsored research has shown that some Class C fly ashes are ementitious (because calcium is combined as calcium aluminates) while other Class C ashes containing similar amounts of elemental calcium are not (1). Fly ashes from modern power plants in Iowa contain significant amounts of calcium in their glassy phases, regardless of their cementitious properties. The present research was based on these findings and on the hyphothesis that: attack of the amorphous phase of high calcium fly ash could be initiated with trace additives, thus making calcium available for formation of useful calcium-silicate cements. Phase I research was devoted to finding potential additives through a screening process; the likely chemicals were tested with fly ashes representative of the cementitious and non-cementitious ashes available in the state. Ammonium phosphate, a fertilizer, was found to produce 3,600 psi cement with cementitious Neal #4 fly ash; this strength is roughly equivalent to that of portland cement, but at about one-third the cost. Neal #2 fly ash, a slightly cementitious Class C, was found to respond best with ammonium nitrate; through the additive, a near-zero strength material was transformed into a 1,200 psi cement. The second research phase was directed to optimimizing trace additive concentrations, defining the behavior of the resulting cements, evaluating more comprehensively the fly ashes available in Iowa, and explaining the cement formation mechanisms of the most promising trace additives. X-ray diffraction data demonstrate that both amorphous and crystalline hydrates of chemically enhanced fly ash differ from those of unaltered fly ash hydrates. Calciumaluminum- silicate hydrates were formed, rather than the expected (and hypothesized) calcium-silicate hydrates. These new reaction products explain the observed strength enhancement. The final phase concentrated on laboratory application of the chemically-enhanced fly ash cements to road base stabilization. Emphasis was placed on use of marginal aggregates, such as limestone crusher fines and unprocessed blow sand. The nature of the chemically modified fly ash cements led to an evaluation of fine grained soil stabilization where a wide range of materials, defined by plasticity index, could be stabilized. Parameters used for evaluation included strength, compaction requirements, set time, and frost resistance.
