| Popis: | 96 This study aims at examining the influence that the change in temperature and humidity of Glassfibre Reinforced Concrete (GRC) and concrete has on their mechanical properties, by giving consideration to durability. This study consists of three tests. The first test involved a physical property test of GRC that included examinations of dry density, wet density, water absorption, and porosity, establishing a basic physical data of the GRC specimens. The second test investigated whether the mechanical properties would be changed under the influence of the rapid temperature and humidity deterioration of the GRC specimens. The third test, by adding glass fibers into the concrete, analyzed whether or not the concrete’s mechanical properties would be affected by the amount of glass fibres added and the influence of the rapid temperature and humidity deterioration. The study findings show that the GRC specimens, after adding 3% of Taiwanese, Japanese, and British sand respectively, had enhanced durability and mechanical properties with the product from the Taiwanese maker. Under the influence of temperature and humidity changes, the mechanical strength of GRC would decrease, and the change in humidity had greater influence on the attrition rate than the change in temperature. In addition, adding anti-aging agents had no effects on the durability in temperature and humidity changes. Adding glass fibres could indeed increase the mechanical properties of the GRC specimens; the more the glass fibres were added, the better the mechanical properties would be, especially if the amount added was 6%. Furthermore, adding glass fibers could definitely reduce fissure occurrences. Keywords: Glassfibre Reinforced Concrete (GRC); Glass Fiber; Durability |
