5. Preface
Concrete is the most widely used construction material because of its versatility,
economy, availability of raw materials, strength, and durability. Concrete can be
designed to withstand the harshest environmental conditions while taking on the
most inspirational and imaginable shapes and forms. Scientist/Engineers and
academicians are continuously working for better concrete from strength and
durability standpoint with the help of innovative chemical admixtures and sup-
plementary cementing materials (SCMs). In addition, the use of SCMs conserves
energy and has environmental benefits because of reduction in carbon dioxide
emission as a result of reduction in manufacture of Portland cement. Strict air-
pollution controls and regulations have produced an abundance of industrial
byproducts that can be used as supplementary cementitious materials. Typical
examples are fly ash, silica fume, ground granulated blastfurnace slag, metakaolin,
rice husk ash and natural pozzolans which can be used incorporated in concrete
addition or as partial cement replacement.
Supplementary cementing materials are often used in concrete mixes to reduce
cement contents, improve workability, increase strength and enhance durability
through hydraulic or pozzolanic activity. Utilization of these byproducts in
cement/concrete not only prevents them from being land-filled but also enhances
the properties of concrete in the fresh and hardened states.
This book is an attempt to consolidate the published research related to the use
of SCMs in cement and concrete. This book is intended to cater to the needs of
graduate students, researchers, concrete technologists and practicing engineers.
The book 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.
We would like to place on record our immense sense of gratitude to acade-
micians, scientists, concrete technologists, and our colleagues and friends globally
vii
6. who have contributed significantly in the broader area of concrete technology, and
our sincere appreciation and acknowledgement to the published work of the
researchers on the subject, which has been referred in this book.
We are also extremely grateful to Springer for publishing the book in an
excellent form in the shortest possible time.
We owe our sincere thanks and irrepayable gratitude to our families and friends
whose consistent encouragement and love have been a tremendous impetus for the
completion of this book.
