A number of gloss fiber reinforced cement composites currently on market were investigated with regard to the alteration of mechanical properties over time. Among these were several so-called alkali-resistant glass fibers (AR-GFRC) and a system consisting of E-glass fibers with a polymer-modified cement matrix [Forton (P)GFRc]. such as strain at ultimate tensile stress, bending strength, and impact strength were initially higher for the AR-GRFC than for the (P)CFRC. However, the AR-GFRC system showed a consider- able decrease of these properties over time, resulting over the long term in a lower level than for (P)GFRC. Various alkali-resistant glass reinforced cements showed a difference in the level of deterioration.
