Metakaolin Effect On Geopolymers Properties

This book delves into the world of metakaolin (MK) and its impact on the properties of geopolymers. Beginning with an introduction to the abundance and versatility of kaolin, the author explores how calcination transforms it into the highly reactive material known as MK. The book investigates the incorporation of MK into different types of geopolymers and examines how factors such as precursor type and fineness, MK fineness, activator type and concentration, curing conditions, and testing age influence the resulting properties. Through a meticulous evaluation of prior studies, the text presents valuable insights into workability, setting time, density, compressive strength (with specific focus on slag, fly ash, and other precursors), flexural strength, splitting tensile strength, elastic modulus, porosity, water absorption, shrinkage, carbonation resistance, corrosion resistance, and other durability aspects. Drawing upon a wealth of knowledge, this work serves as a comprehensive reference for researchers and offers a roadmap for future investigations.

This series will present twenty short, sharply-focused tracts, each one covering one of the many aspects of concrete technology: materials, design, construction, testing, and other significant aspects. Volume 1 provides a complete overview of the mineral admixtures used in concrete, including silica fume, slag, rice-husk ash, fly ash, and natural pozzolans. This book will include the mineral and chemical composition of the admixtures, their chemical reactions with cement and as a method of recycling.

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.
