Public ISBD Titre : The behaviour of epoxy resins with particular reference to the influence of bond strength and curing conditions on the performance of screeds Type de document : texte imprimé Auteurs : Salah Eddine Boudraa, Auteur ; D. R. Plum, Directeur de thèse Editeur : University of Newcastle Upon Tyne Année de publication : 1985 Importance : 154 f. Présentation : ill. Format : 27 cm. Note générale : Mémoire de Master : Génie Civil : Angleterre, University of Newcastle Upon Tyne : 1985 Bibliogr. f. 155 - 165 . Annexes: [162 f.] Langues : Anglais (eng) Mots-clés : Epoxy  resin  concrete Polymers Inherent  stickiness Binders Indirect  tensile  strengths Index. décimale : Ms00185 Résumé : This thesis aimed to begin the work of investigating the physical and mechanical properties of epoxy resin concrete and to assess the influence of different curing regimes on the behaviour of such resins. It is started by an introduction into the chemistry of polymers. Since polymers are used as binders in resin concrete, to grasp the behaviour of such polymers is very important in the understanding of the behaviour of polymer concrete. A description of the different kinds of concrete using polymers is then carried out. Practical considerations as well as theoretical ones are considered for the epoxy resin concrete flooring. In the experimental procedure a new technique of testing as well as new instrumentation have been thought of to assess the bond strength ability. And this has been done for the five different types of epoxy resins available used throughout the experimental procedure. Because of the inherent stickiness of the binders and the small quantities involved in the mixing, new techniques for moulding and demoulding the specimens have been used to avoid the problems arising from such difficulties. The compressive and indirect tensile strengths of the five different types of epoxy resins have been assessed together with the influence of different curing regimes including variations in length of cure and curing temperatures. The behaviour of the epoxy resins under different rates of loading and periods of cure was looked at. The compressive modulus of elasticity was calculated for the fastest rate of loading and compared with the values given by the manufacturers when available. The other values of compressive and indirect tensile strengths were also compared with the values in the literature when available. Finally, a modest preliminary work into the creep properties, due to the lack of precise instrumentation within the time allowed for the practical work (instantaneous strain measurement devices, compressive loading machine capable of self adjustment...) was carried out. Therefore the creep data presented is merely sufficient for comparison purposes between the different epoxy resins available or for grasping the importance of creep for such materials when looking at the data representing the amplitude of the creep strains.
