LONG-TERM DURABILITY OF GRC COMPOSITES
Much attention has been paid to the research and development of glass fibre reinforced cements and concretes (GRC) in the last two decades. These composite materials came into existence as a practical construction material due to their many advantageous properties, e.g. increased impact and flexural strength, higher durability under different loadings, as well as at higher temperatures etc. The grc material was successfully introduced in different fields of the building industry, e.g. as cladding panels (wall units, window units, spandrels, mullions, and column covers), further as permanent shuttering, ventilation ducts, noise barriers, garden and street furniture, such as planters, litter bins and street signs, and as junction boxes for electric cables, Hannant (1978).
