Supplementary cementing materials (SCMs), such as fly ash, slag, silica fume, and natural pozzolans, make a significant difference to the properties of concrete but are rarely understood in any detail. SCMs can influence the mechanical properties of concrete and improve its durability in aggressive environments. Supplementary Cementing Materials in Concrete covers the chemical, physical, and mineralogical properties of SCMs; their chemical reactions; and the resulting changes in the microstructure of concrete. The author links the properties of the material at the microstructural level with its behavior in laboratory tests, and, in turn, to the performance of the material in concrete structures under field exposure. He explains how SCMs influence the mechanical properties of concrete and improve its durability and also covers how various SCMs influence hydration reactions and the evolution of the pore structure and pore-solution composition. However, SCMs are not a panacea for concrete and improper use may be injurious to certain properties. Achieving the maximum benefit from SCMs requires an understanding of the materials and how they impact concrete properties under various conditions. Drawing on the author’s 30 years of experience, this book helps engineers and practitioners to optimize the use of supplementary cementing materials to improve concrete performance.

This book is an attempt to consolidate the published research related to the use of Supplementary Cementing Materials in cement and concrete. It comprises of five chapters. Each chapter is devoted to a particular supplementing cementing material. It is based on the literature/research findings published in journals/conference proceeding, etc. Topics covered in the book are; coal fly ash, silica fume (SF), granulated blast furnace slag (GGBS), metakaolin (MK), and rice husk ash (RHA). Each chapter contains introduction, properties of the waste material/by-product, its potential usage, and its effect on the properties of fresh and hardened concrete and other cement based materials.

The use of Supplementary cementing materials (SCMs) dates back to the ancient Greeks who incorporated volcanic ash with hydraulic lime to create a cementitious mortar. Supplementary cementing materials (SCMs) subsidize to the properties of hard-edged concrete through hydraulic or pozzolanic movement. Usual examples are fly ashes, slag cement, and silica fume. These can be used exclusively with Portland or blended cement or in different combinations in order to concrete to make concrete mixtures more economical, reduce permeability, increase strength, or influence other concrete properties. The key to concrete's success is its versatility and no other sector of the construction industry utilizes this attribute more than the manufactured concrete products industry. Concrete can be designed to withstand the harshest environments while taking on the most inspirational forms. This book is an attempt to integrate the current trends and reviews related to the use of Supplementary Cementing Materials in cement and concrete. The book is packed with a range of topics from understanding the fundamental science behind using Supplementary Cementing Materials (SCMs) to practical examples of their use in real situations. It includes a wide range of studies on the properties of the waste material/by-product, its potential usage, and its effect on the properties of fresh and hardened concrete and other cement based materials. With these issues and complexities in mind, the purpose of this book is to provide policymakers with information and analysis necessary to develop regulations and design instruments that have the greatest potential to remove impediments to increased SCM consumption in world and optimize SCM utilization in a manner that is consistent with evolving market conditions in the short, medium, and long terms. It describes how supplementary cementitious materials (SCMs) and blended cements are used in paving concrete as one way of increasing the overall sustainability of concrete mixturesThis book serves as a guiding tool for students, engineers, and practitioners to optimize the use of supplementary cementing materials to improve concrete performance.

The aim of this book is to present the latest findings in the properties and application of Supplementary Cementing Materials and blended cements currently used in the world in concrete. Sustainability is an important issue all over the world. Carbon dioxide emission has been a serious problem in the world due to the greenhouse effect. Today many countries agreed to reduce the emission of CO2. Many phases of cement and concrete technology can affect sustainability. Cement and concrete industry is responsible for the production of 7% carbon dioxide of the total world CO2 emission. The use of supplementary cementing materials (SCM), design of concrete mixtures with optimum content of cement and enhancement of concrete durability are the main issues towards sustainability in concrete industry.

This volume represents the current knowledge on the effect of SCMs (slag, fly ash, silica fume, limestone powder, metakaolin, natural pozzolans, rice husk ash, special SCMs, ternary blends) on the properties of fresh and hardened concrete (e.g. early strength development, workability, shrinkage) and curing requirements. Other topics treated in the book are postblending vs preblending, implications of SCM variability, interaction between SCM and commonly used admixtures (e.g. superplasticizers, air entrainers).
