The book deals with modern theoretical concepts related to the impact of fly ash and metakaolin admixtures on structure formation processes of concrete. Results of the effect of fly ash, metakaolin and their composition on properties of self-compacting and self-leveling concrete are presented. Based on mathematical models, obtained using mathematical experiments planning methodology, the impact of the main factors and their combination on workability, strength and other properties that determine efficiency and durability of concrete are analyzed. Using calculated dependencies, a methodology for designing optimal compositions of concrete containing active mineral admixtures and superplasticizers is proposed. Features of industrial production of concrete for the proposed compositions are discussed. The book is intended for specialists working in the production of concrete and reinforced concrete products and elements. It can also be used by construction engineers to design compositions of cost-effective self-compacting and self-leveling concrete as well as to determine the rational direction of using technogenic raw materials like ash and metakaolin.

Written to meet the requirements of engineers working in construction and concrete manufacturing, Mineral Admixtures in Cement and Concrete focuses on how to make more workable and durable concrete using mineral admixtures. In particular, it covers pulverized fuel ash (PFA), blast furnace slag (BFS), silica fume (SF), rice husk ash (RHA), and metakaolin (MK), as well as some new admixtures currently under investigation. For each mineral admixture, the book looks at manufacturing and processing, physical characteristics, chemical and mineralogical composition, quality control, and reported experiences. It also examines the provisions of national standards on the admixture’s addition to cement and concrete. References to microstructures and chemistry are kept to a minimum and only discussed to the extent necessary to help readers apply the admixtures in practice. The book also addresses hydration, presenting the relevant chemistry and detailing the impact of adding mineral admixtures to concrete. A chapter on strength and durability explains the mechanisms, models, and standards related to concrete deterioration and how to mitigate carbonation, alkali-aggregate reactions, chloride attack and corrosion of reinforcement, external and internal sulphate attack, decalcification, and freeze-thaw action. This book is a useful reference for practicing engineers and students alike. It brings together, in one volume, information on the materials, hydration, and the strength and durability of cement and concrete with mineral admixtures. Offering a deeper understanding of mineral admixtures, it encourages engineers to more effectively use these and other wastes in cement and concrete to support more sustainable growth of the cement and construction industry.
