Handbook of Coatings for Concrete




Preface

This handbook provides detailed information on the use of coatings to protect concrete from atmospheric exposure and has been written by experts in the field in Europe and

the Far East and edited by two well known names in concrete coatings research. It reviews the present state of knowledge of the different generic types of coatings

commonly used, highlights specific needs in the protection of concrete, discusses the standardised testing carried out and has a useful section on typical case histories. Each chapter is illustrated by clear diagrams and photographs where necessary and there is

a useful bibliography at the end of each chapter.


The handbook starts with a comprehensive introductory chapter to set the scene;

why coat concrete, with what and how should it be carried out. The following chapters of the book essentially take the points made here and expand on them. Firstly the types of coatings typically used are described, but before this, the second chapter gives an overview of paint technology, so that those readers not familiar with this subject will be

able to understand the concepts discussed. For each generic coating type, an easily understood description of the chemistry is given followed by the properties and per-

formance of the coatings and finally typical uses. Acrylic and cementitious coatings form a very important segment of the concrete

protection market and three chapters are devoted to these coatings. In addition, the other widely-used generic resin systems, epoxy and polyurethane, are also given very detailed coverage.


The handbook then turns to some specific problems with concrete and how coatings can be used to overcome these. Chapters focus on the protection of rebars in reinforced concrete structures, anti-carbonation coatings, and crack-bridging by coatings. There are also chapters dealing with the aesthetic properties of coatings, including biological growth, its evaluation, and the use of biocides.


How to select the correct coating, and the range of international test procedures needed are covered in one chapter as is the very important topic of surfixe preparation. This topic is covered to some extent in the previous chapters on the generic resins, but is given a more detailed treatment, since even when the best coating system is selected, if the surface has not been prepared properly, the desired performance will not be achieved.
