Abstract
This paper deals with accelerated and long-term durability tests of glassfibre-reinforced cement composites. AR glassfibres REZAL, ESAP and SVUS 16, developed in Czechoslovakia, and Cem-FIL 1 fibres developed in the United Kingdom were applied. REZAL and ESAP fibres are of a low zirconium dioxide content, SVUS 16 and Cem-FIL 1 fibres are of a high zirconium dioxide content. The accelerated and the long-term ageing process were studied. The modulus of rupture was determined after 28, 90, 180, 360, 720 and 1080 days, and 6 years of ageing. The investigated glassfibre types have shown a high alkali resistance, mostly when dry curing was applied. Within the testing period of six years, glassfibres of low as well as high zirconium dioxide content show similar behaviour in the cement matrix.
