The nature of concrete is rapidly changing, and with it, there are rising concerns. Thoroughly revised and updated, this fourth edition of Concrete Mix Design, Quality Control and Specification addresses current industry practices that provide inadequate durability and fail to eliminate problems with underperforming new concrete and defective testing. Many specifications now require additional criteria in an attempt to improve durability or other properties. This book discusses the trend towards adding performance requirements to existing prescriptive specifications. It also explores the matter of prescription versus performance specification and especially the specification of non-strength-related performance such as durability. What’s new in the Fourth Edition: Examines water-to-cement ratio as a declining criterion of quality and durability Discusses the diminishing availability of suitable natural sands and growing industry concerns regarding the environmental impact of their use Considers advances in concrete admixtures and their ever-increasing use Advocates reliability of testing as a vital feature of the shift from prescriptive to performance specifications Addresses cement replacement materials as they relate to greenhouse gas and sustainability Concrete Mix Design, Quality Control and Specification explores producing, designing, controlling, or specifying concrete, and addresses issues related with sustainability and the impact of new concrete materials such as ready mixed geopolymers, magnesium oxide, and calcium carbonate. The text is an ideal resource for concrete technologists, producers and specifiers, and contractors on large projects

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. Concrete has become a complex material, generating hundreds, if not thousands, of PhD theses and a substantial number of computerised 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 accompanying website, www.kenday.id.au, offers free programs and access to continually updated advice.

The latest edition of this established book has been brought completely up-to-date with recent advances in concrete technology. A practical reference, it illustrates how computers and high-tech testing equipment can save time and money in controlling concrete. The philosophies and methods can be applied to a full range of types of concrete and on straight forward to advance construction projects. On the CD ROM the author gives live colour displays with spoken commentaries of all Conad products and their origins and provides free working mix design and QC programs.

Infrastructure work is still declining, although there are plans to release £1.3bn worth of road network schemes over the next few years. Network rail has published plans to spend £38bn on upgrade works over the next five years. Water firms are to bring forward $400m of work into this financial year. Spon's Civil Engineering and Highway Works Price Book 2015 from AECOM gives costs for both general and civil engineering works and highway works, and provides a full breakdown of labour, plant and material elements, with labour rates updated in line with the latest CIJC wage agreement. Beyond prices, it can be used as a comprehensive work manual for the UK’s civil engineering, surveying and construction business. Use the access code inside the front cover of the book to get set up with internet access to this edition until the end of December 2015. We now provide SPON’S Online, a versatile and powerful online data viewing package, which replaces the estimating software and ebook of recent years. This 29th edition incorporates a comprehensive review throughout: Updated to come into line with the CESSM4 structure as well as MMHW And with an expanded range of rail elements
