Concrete Mix Design, Quality Control and Specification



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.

The most fundamental change is the recognition that water to cement (w/c) ratio is not the best available criterion of quality and durability. 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.

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.
