This thesis was submitted in partial fulfillment of the requirements for the Degree of Doctor of Philosophy at University of New South Wales, Department of Civil Engineering Materials. Studies to determine the influence of monomers and mixtures of monomers (and subsequently polymers and copolymers respectively) on the characteristics of hydrating cement in premix polymer - cement materials are presented in the first part of this thesis. The second part of this thesis was concerned with the study of the influence of two premix polymer additives, sarabond and methyl methacrylate, on the aggregate - mortar interface characteristics. The effect that changes in adhesion and friction angle, the interface properties, have on the strength and deformation behaviour of concrete was also investigated. It is clear from this investigation that few of the premix polymer (or copolymer) systems contribute to any substantial improvement in the strengths and elastic modulus of concrete, unlike polymer impregnated concrete systems. It is also apparent that the interaction between the hydrating portland cement and the monomer affects the properties of the fresh and hardened concrete in an often deleterious way. Any benefit from the use of monomer or polymer systems in premix polymer-cement concretes must be sought in their influence on other concrete properties, (e.g. Fracture toughness, extensibility, improved resistance to chemical attack). An examination of some of these other properties constitute part of a parallel study to this thesis. (TRRL)
