POLYPROPYLENE-REINFORCED CEMENT COMPOSITES FOR SURFACE REINFORCEMENT OF CONCRETE STRUCTURES

Possible uses of fibre reinforced cement as local surface reinforcement to improve the serviceability of concrete structures are reviewed. New types of cement composites, based on polypropylene film, show considerable promise as alternatives to asbestos cement or grc for this purpose. Tensile and flexural tests indicate that these new composites have the high strain capacity required for controlling crack development in the concrete and that the long-term effectiveness is likely to be better than that of currently available grc. The tests described covered a range of curing and exposure conditions, including prolonged immersion in hot water and exposure to ultra-violet radiation. In general no significant changes in strength or strain capacity resulted from any of the accelerated 'durability' tests. The use of such materials for permanent formwork on concrete structures such as bridge decks could show substantial economic benefits when related to overall construction and maintenance costs.
