2011 Gaynor Award Recipient

Ken Day, Retired, Concrete Advice, Pty. Ltd., Melbourne, Australia

Ken Day is a world renowned expert on concrete quality control. He fashions himself as an evangelistic concrete technologist willing to preach to anyone willing to listen. Ken’s expertise has been on concrete mix design, quality control and specifications. He has worked in the ready mixed concrete and precast industries. He has also worked as a consulting structural engineer, a university lecturer, and a general investigator and legal expert witness of defective concrete.

Ken Day is a pioneer in developing computerized mix design methodology and statistical quality control of concrete. He has used aggregate specific surface concepts in his mix design process to achieve workable concrete mixtures for different placement methods. He has developed multigrade, multivariable cusum (cumulative sum) methodology for quality control by which the various measured properties of concrete can be evaluated to identify the potential for failures before they occur. These concepts were used to develop the ConAd software that is now incorporated in software provided by a major company providing services to the concrete industry. His concepts have been used on several international high profile projects, but one that he is proudest of is when it was used by his younger son, John, to control concrete production for Petronas Towers, at that time the world’s tallest building, and a standard deviation of 450 psi was attained on the last 200 results of concrete strengths averaging over 14,000 psi.

Since the mid 1950s, Ken Day has authored numerous papers and presented at various international conferences across the globe in on a wide range of topics on concrete technology, most of which are posted on his website www.kenday.id.au. He is also author of the internationally acclaimed book – Concrete Mix Design, Quality Control and Specification, now in its 3rd edition. 

Ken Day has been a strong proponent of the evolution towards performance-based specifications for concrete and was personally responsible for bringing about the current system of specification on this basis in Australia 30 years ago. In more recent years he has been very supportive of the NRMCA P2P Initiative and has written and spoken at many venues in support of his contention that performance specifications, passing control of mix design and quality control to the concrete producer, are essential for the achievement of low variability and optimum performance.

Ken Day graduated from Manchester University in the UK in 1952. He is an Honorary Member of the Concrete Institute of Australia; Fellow of the Institute of Engineers, Australia; Fellow of the Institute of Concrete Technologists, U.K.; Fellow of the American Concrete Institute and received a lifetime achievement award from CANMET/ACI.

At age 80, having nominally retired ten years ago, he is still determined to bring about P2P in USA and to complete a final 4th edition of his book.
