There is an increasing need for new materials and methods for rapid but durable repair of concrete. The author outlines the main properties and reports on some aspects of durability derived from laboratory investigation. Micro-fibre reinforced polymer cementitious materials provide early strength materials and can be considered dimensionally stable. Compressive and bonding strengths show a satisfactory strength. Meanwhile, the micro-fibre reinforced polymer cementitious materials had a low permeability which doesn’t allow water vapour to diffuse through the matrix. Details are expected to be given of successful applications on most of all concrete structures.
