The rapidly changing scene in concrete technology necessitates this fourth edition. Obviously I am aware of these changes, but being retired from active participation in concrete production and control, I have brought in two carefully selected coauthors in addition to obtaining input from many people I consider to be leading experts in their fields. This, combined with greenhouse gas and sustainability considerations, has caused cement replacement materials to be viewed in a new light. In the future, little, if any, concrete will be produced without at least one component of this large range of materials. The diminishing availability of natural sand conforming to preconceived ideal gradings has opened up the field for crusher fines, creating a new imperative to better understand their production and use. It is not surprising that higher strengths and higher heights of pumpability are available, or that self-compacting concrete is becoming popular—and there will always be new admixtures.
Mix proportioning of concrete remains an area of interest for all concrete technologists and engineers, both academics and practitioners. The tone of the book is set in this chapter in that it is a book meant more for practising engineers and concrete technologists rather than research or academic professionals. Chapter 1 on specification is followed by three chapters on ingredient materials, and these are succeeded by Chapter 5, on the properties of concrete. Chapter 6 deals with specifications. This chapter highlights the necessity of specifying performance s rather than compressive strength alone, as had been the practice until recently. This is certainly an appropriate step forward in accordance with current understanding.

This has led to an arrangement for me to present a whole day seminar in Silver Spring, Washington, in June , 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. This is very much not a handbook on how to comply with established standards but rather a view on how those standards, and other entrenched attitudes, should be revised to more nearly reflect reality and enable progress. The reason is the electronic devices divert your attention and also cause strains while reading eBooks.

Стратмор закрыл дверцу холодильника и без тени волнения взглянул на Чатрукьяна. - Ты имеешь в виду работающий монитор. Чатрукьян растерялся. - Так вы обратили внимание.
ГЛАВА 33 Токуген Нуматака смотрел в окно и ходил по кабинету взад-вперед как зверь в клетке. Человек, с которым он вступил в контакт, Северная Дакота, не звонил. Проклятые американцы. Никакого представления о пунктуальности.
