This new edition of Ken Day's established professional guide has a dual purpose. It provides comprehensive, readily understandable assistance to concrete producers, large and small, in the design and control of their product, and it looks as far as possible into the future of concrete. Self-compacting concrete is of rapidly increasing importance; strengths are constantly rising; quality control is a must; and survival necessitates maximum economy. Portland cement production is identified as a major source of CO2, and its use must be minimized. Antiquated specifications and antiquated control methods must go. Concrete has become a complex material, generating hundreds, if not thousands, of PhD theses and a substantial number of computerized systems. Having originated the first of such systems, Ken Day now shows how to apply the principles with or without elaborate systems. Such systems pay big dividends to the larger producer but this book still shows the small producer how to achieve competitive mix designs and close quality control without either excessive expenditure or extensive theoretical study. The CD-ROM of the 2nd edition is now replaced by a website, www.kenday.id.au which offers free programs and the prospect of continuous updating of advice.This new edition of Ken Day's established professional guide provides comprehensive, readily understandable assistance to concrete producers in the design and control of their product, and looks as far as possible into the future of concrete.
