Book Description
Since it was first recognized as a mineral admixture for concrete in the 1930's, fly ash has been the subject of worldwide study as researchers work to maximize its economical and environmental benefits. In recent years, investigations have focused on the physical, chemical and mineralogical characteristics of fly ash and their specific correlation to the performance of concrete. This book collects the latest results from these various studies and offers a complete review of the advantages of fly ash as an admixture in concrete, including strength development and improved chemical resistance and durability. A review of the current international standards on fly ash usage is provided, in addition to an extensive reference list and a complete survey of various other fly ash products, such as bricks, mineral wool and gypsum wall boards, as well as the use of fly ash in waste management.

Book Description
When used as an addition and binder component, fly ash has become an indispensable construction material for many concrete applications. The conditions produced in power stations when firing fine pulverized coal result in the formation of a reactive, flour-fine, pozzolanic mineral material from the accompanying rock in the coal. Owing to its specific characteristics it has a positive impact on the properties of fresh and hardened concrete and facilitates cost-effective production of high-grade, durable concretes. The authors of this handbook have combined the latest discoveries from the field of research with practical experience of the use and effects of fly ash in concrete. This handbook provides the necessary information and makes interesting suggestions for selective use of fly ash in concrete.

Book Description
Concrete industry is one of the main industries using large proportion and volume of our natural resources. Ordinary Portland Cement is an important source for the emission of carbon dioxide into the atmosphere because of burning fuel and raw materials' decomposition during the production process of cement. Due to the increasing demand in concrete, one of the most effective and reliable ways to reduce the negative impact on the environment in the concrete industry is through the use of waste and by-product materials such as aggregates and ordinary portland cement replacement in concrete. The prospect of producing structural lightweight concrete using large volume of waste materials and by-products is investigated in this current study. The lightweight material used as coarse aggregate comprised of expanded shale and expanded clay. While the waste and by-product material comprised of a high volume (50% and 70%) of type C and type F fly ash, as replacement for cement by volume. The mechanical properties such as compressive strength, split-tensile strength, flexural strength, modulus of elasticity and drying shrinkage for up to 28 and 56 days are investigated as well as slump and unit weight for fresh density. The durability properties such as abrasion resistance, water absorption, resistance to chloride ion penetration and freeze and thaw resistance are also investigated. All lightweight concrete containing 50% fly ash class C and F replacement showed adequate strength in the mechanical properties. While lightweight concrete with 70% fly ash both class C and F exhibited strength lost compared to other concrete samples. Test results showed that the early ages of drying shrinkage of ordinary Portland cement and fly ash are similar but with the growth rate of drying shrinkage in OPC, it is expected for concrete incorporated with fly ash to exhibit good resistance to drying shrinkage. Test results also indicated that, concrete incorporated with fly ash showed good resistance to chloride ion penetration and there was no significant difference in abrasion for either OPC or fly ash incorporated concretes. There was significant difference in water absorption of the concrete containing fly ash. However, concretes with fly ash performed poorly and could not resist exposure to freeze and thaw mechanism especially concretes incorporated with 70% fly ash F.

Book Description
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.
