TABLE OF CONTENTS Two aspects of organic material considered as cohesion admixtures were dealt in this chapter.
The first concerns adhesive bonding or gluing, general adhesion and an interesting associated application, the formulation of organic matrix composites. The second is centered around concrete admixtures. We can try to remember a few general ideas.
The study of gluing is quite disconcerting. Theories and techniques of gluing often display divergences which are difficult to surmount. There remains a lot of work to be done in this field. It is not a sufficient reason to ignore or abandon this type of construction technique but there is still a long way to go. We could however state that the development of gluing in construction must not be left to the specialists; it concerns all, designers, architects, engineers, multi-disciplinary researchers including those in life sciences. We must aim at a global design.
Organic matrix composites, the material of the future, is being developed in the civil engineering field but has still not given rise to significant works in the physicochemical arena. Their introduction is too recent for possible problems to arise that require in-depth structural studies outside the laboratory of producers.
Today admixtures have become a separate constituent of concrete. The essential part of production concerns the rheological admixtures as such plasticizers, water reducers and their higher counterparts superplasticizers and high range water reducers but the other types of admixtures have also become common. Concrete formula used in all...
