The purpose of this writing this book is to express the properties of Rise Husk Ash (RHA) based geopoylmer incorporate with, (GGBS) at ambient curing conditions, which ican be trated as a substitute to the (OPC). The work constructs with subsidizes for fabrication of innovative eco-friendly binders in concrete. Even though, present several reasearch that evaluate the performance of geopolymer. using numerous kinds of source material, much of this research has concentrated on rice husk ash as primary source material. Only inadequate studies till conducted in large-volume mortars of RHA-based geopolymer, using sensible compressive strength and no further studies with GGBS have been combined.

A geopolymer is a solid aluminosilicate material usually formed by alkali hydroxide or alkali silicate activation of a solid precursor such as coal fly ash, calcined clay and/or metallurgical slag. Today the primary application of geopolymer technology is in the development of reduced-CO2 construction materials as an alternative to Portland-based cements. Geopolymers: structure, processing, properties and industrial applications reviews the latest research on and applications of these highly important materials.Part one discusses the synthesis and characterisation of geopolymers with chapters on topics such as fly ash chemistry and inorganic polymer cements, geopolymer precursor design, nanostructure/microstructure of metakaolin and fly ash geopolymers, and geopolymer synthesis kinetics. Part two reviews the manufacture and properties of geopolymers including accelerated ageing of geopolymers, chemical durability, engineering properties of geopolymer concrete, producing fire and heat-resistant geopolymers, utilisation of mining wastes and thermal properties of geopolymers. Part three covers applications of geopolymers with coverage of topics such as commercialisation of geopolymers for construction, as well as applications in waste management.With its distinguished editors and international team of contributors, Geopolymers: structure, processing, properties and industrial applications is a standard reference for scientists and engineers in industry and the academic sector, including practitioners in the cement and concrete industry as well as those involved in waste reduction and disposal. Discusses the synthesis and characterisation of geopolymers with chapters covering fly ash chemistry and inorganic polymer cements Assesses the application and commercialisation of geopolymers with particular focus on applications in waste management Reviews the latest research on and applications of these highly important materials

The progressive deterioration of concrete surface structures is a major concern in construction engineering that requires precise repairing. While a number of repair materials have been developed, geopolymer mortars have been identified as potentially superior and environmentally friendly high-performance construction materials, as they are synthesized by selectively combining waste materials containing alumina and silica compounds which are further activated by a strong alkaline solution. Geopolymers as Sustainable Surface Concrete Repair Materials offers readers insights into the synthesis, properties, benefits and applications of geopolymer-based materials for concrete repair. • Discusses manufacturing and design methods of geopolymer-based materials • Assesses mechanical strength and durability of geopolymer-based materials under different aggressive environmental conditions • Characterizes the microstructure of these materials using XRD, SEM, EDX, TGA, DTG and FTIR measurements • Describes application of geopolymer-based materials as surface repair materials • Compares environmental and cost benefits against those of traditional OPC and commercial repair materials This book is written for researchers and professional engineers working with concrete materials, including civil and materials engineers.

Portland cement based concrete is the most versatile, durable and reliable building material. Unfortunately, the production of Portland cement is environmentally unfriendly. An interesting alternative is provided by alkali-activated geopolymer materials (AAGM). This book focuses on fly ash-based alkali-activated geopolymer concrete, its production and characteristic properties. The re-use of waste materials and industrial by-products, such as fly ash, is not only economically of interest but also helps to reduce carbon dioxide emissions. The carbon footprint of these materials is much lower than that of concrete using ordinary Portland cement. They thus offer new sustainable solutions to the construction industry. Keywords: Geopolymers, Geopolymer Concrete, Alkali-activated Geopolymer Materials (AAGM), Portland Cement, Fly Ash-based Geopolymer Concrete, Reduction of Carbon Dioxide Emissions, Concrete Applications, Self-Compacting Concrete, High-strength Concrete, High-performance Concrete.

GEOPOLYMER AS GREEN CONSTRUCTION MATERIALS RESEARCH describes about different important factors (e.g. NaOH molarity, activator-to-fly ash ratios, curing condition, etc.) influencing the processing of the fly ash-based geopolymer were investigated. These experimental results are utilized to propose a new method for geopolymer cement processing and the design of geopolymer concrete mixtures. Experimental data on the characterization and properties of the geopolymer cement and concrete are then presented. Some case study about the geopolymer materials also has been presented in this booklet. Final part of this book also describes the application of these geopolymers as lightweight materials, geopolymer brick, pilot plant for geopolymer brick/block making machine, and some preliminary study on geopolymer coating and aggregate.

DEVELOPMENT OF GEOPOLYMER FROM POND ASH-THERMAL POWERPLANT WASTE Explains 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.
