Concrete Mix Design - Quality Control and Specification 3rd Edition







Introduction

Between writing this third edition and its actual publication, there have been some

possibly quite significant developments in my situation. The assumption during

writing the book was that I was fully retired and might contribute further to the

future of concrete technology only via this book and my website, if at all.

A change arose initially from the intention of Canmet/ACI to award me recognition for my

contributions to concrete quality control at their symposium in May 2006. This

has led to an arrangement for me to present a whole day seminar in Silver

Spring, Washington, in June 2006, under the auspices of NRMCA and others,

in an attempt to bring about a change in American practice from quality control

by the purchaser to control by the producer, as advocated in this book.

A further development has been an invitation to join a partnership of

the Canadian company Contek with the Shilstones (father and son, perhaps the

best known names in concrete technology in USA) in an endeavour to produce

world-leading software and to market and support it throughout the world.

You, the reader, will have to consult my website for

information as to the outcome of the above. I have not made changes in the rest

of this introduction or in the text as a whole as a result of these developments but

considered that readers should be made aware of them, and may be interested to

see my views and intentions prior to their occurrence.
