| Abstract | ||
| In this work, the durability of glass fiber reinforced mortar, GFRM, was experimentally investigated. The evaluation was based on the performance of the composite under three mechanical tests (compression, indirect tension and flexural). The GFRM specimens were exposed to four-environmental attack. These include air, water, chloride and sulfate. The specimens were tested after 28, 180, 360 and 540 days. The effect of fiber volume fractions, (V+=0, 1, 2 and 3 %) was considered. The effect of using sulfate resistant cement and addition of 10% silica fume to the ordinary Portland cement on the durability of the GFRM was undertaken. Test results indicated that the addition of glass fiber has a small effect on the compressive strength of GFRM specimens. The presence of glass fiber in the cement-based mortar enhanced the relative compressive strength of the composite stored in sulfate. There is a general increase in the tensile and flexural strengths with increasing fiber volume fraction. The addition of 10% silica fume enhanced the compressive and tensile strengths of the specimens stored in water media at all ages but for specimens stored in sulfate it enhanced up to 180 days and after that they decreased. Sulfate resistant cement enhanced the compressive and tensile strengths of GFRM stored in sulfate media compared to those specimens stored in water media. | ||
