Glass fibre reinforced water-resistant gypsum-based composites
AbstractThe effect of length and content of E-type glass fibre on the strength properties (flexural, tensile and impact) of water-resistant gypsum binder was studied. The data show that maximum strength was obtained on using 4·0% of glass fibres 50 mm long. The performance of gypsum binder and that of plain plaster composites in water was investigated by immersion. The results show absence of leaching of the matrix in gypsum binder as compared with plain plaster composites. The mechanical properties of gypsum binder composites obtained on curing in high humidity ( relative humidity at ) and in water, in air and by natural weathering were compared. In general, an increase in composite strength was noticed but best results were found when the composites cured in high humidity.The durability of glass reinforced composites has been assessed after exposure to alternate wetting and drying cycles at 27–50°C. The strength reduced and the weight loss increased with the increase in temperature. The maximum fall in strength occurs at 50°C.
