Mineral trioxide aggregate (MTA) was invented in the mid-1990s at Loma Linda University, USA, with the aim of introducing a material for use as a root-end filler that would set and develop its properties in the presence of moisture. MTA is a mixture of Portland cement and bismuth oxide, which is added to enhance the radiopacity of the material. These two components are mixed with water to produce hydrated cement. This book concisely presents information on diverse aspects of MTA and its use with a view to making it more widely available to clinicians and researchers. The topics covered include the development of MTA and its introduction into clinical dentistry, its chemical composition and setting characteristics, manipulation and placement, material properties, reactivity and the influence of environmental factors. The clinical applications are clearly explained and related innovations and further materials currently available on the market are also discussed.

The effect on clays and the stabilizing effect of damp clays on ungraded natural aggregates germinated an idea upon which a mortar theory for bituminous mixes might be based. This mortar theory, stated briefly, is the formation of thin films of bituminous binder upon the minute particles of a mineral dust to form a bituminous mortar, and the mortar so prepared to be used to bond aggregates together into a bituminous mixture suitable for paving purposes. In order to test the validity of the mortar theory as quickly as possible, known methods of producing such thin films were studied and the impact process selected for this purpose in further tests.
