Glassfibre reinforced concrete (GRC) is the most complex material widely used in current construction practice. It is an unusual composite, in which both the matrix and the reinforcement themselves are composites. This book provides guidance on the properties, its specification, testing and the latest methods for efficient production. Detailed information is presented about the unique aspects of the internal structure and fracture mechanisms of GRC and how the latest advances in nanotechnology are leading towards a fuller understanding of the rational design of GRC and the potential for further improvement of properties beyond those used in contemporary construction practice.
