Handbook on fly ash in concrete

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.

Handbook on fly ash in concrete

Foreword to the First Edition
As an addition and a binder component, fly ash is nowadays an indispensable material for many applications of concrete. Our current level of knowledge and experience is based on a technical development that started in Germany in the mid-1960s and has been continued worldwide with intensive and extensive research work.
The conditions existing in power stations when firing pulverized coal cause a flour-fine, pozzolanic mineral material to form 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 enables high-grade, durable concretes to be produced in a cost-effective manner.
The use of fly ash in concrete is also highly beneficial from an economic and ecological perspective, as the smaller quantities of cement and aggregate used enable valuable resources to be conserved, energy to be saved and pollution and carbon dioxide emissions, which are unavoidable in the production of building materials, to be reduced.
In this book, the authors have combined the latest discoveries from the field of research with practical experience of the use and effects of fly ash in concrete for the user. We hope that this book delivers all the necessary information and provides interesting suggestions for the targeted use of fly ash in concrete, thus promoting the use of this valuable raw material.
Foreword to the Second Edition
After five years, the results of new research into the effect of fly ash in concrete and the properties of fly ash concrete, and their implementation in the rapidly changing regulations on the production of concrete have inspired the authors to extensively revise and update the Handbook on Fly Ash in Concrete. The situation as regards standards relating to this field as of August 2008 has also been incorporated. The authors hope that this Second Edition will prove to be a helpful, practical resource for the production of concrete with fly ash in compliance with the applicable standards.
