This research report investigates the impact of glass fiber on concrete strength development. Concrete of the M50 grade is prepared in accordance with IS codes. Total 30 specimens of cubes, cylinders, and beams are casted, out of which 15 are for 7 days strength testing and remaining 15 are for 28 days strength testing. Concrete specimens with varying glass fiber content (0.5, 1, 1.5, and 2%) by weight of cement were tested for compressive, tensile, and flexural strength at different curing ages. Results showed significant strength improvements with glass fiber inclusion, enhancing compressive, tensile, and flexural properties. However, an optimum fiber content was identified. This study provides valuable insights for designing and applying fiber-reinforced concrete in construction projects, enhancing the durability and resilience of structures. In conclusion, the investigation carries substantial possibilities for improving concrete structure’s performance. By examining mechanical properties of GFRC, the research strives to offer valuable insights capable of improving our knowledge for composite materials in construction engineering.

摘要

This research report investigates the impact of glass fiber on concrete strength development. Concrete of the M50 grade is prepared in accordance with IS codes. Total 30 specimens of cubes, cylinders, and beams are casted, out of which 15 are for 7 days strength testing and remaining 15 are for 28 days strength testing. Concrete specimens with varying glass fiber content (0.5, 1, 1.5, and 2%) by weight of cement were tested for compressive, tensile, and flexural strength at different curing ages. Results showed significant strength improvements with glass fiber inclusion, enhancing compressive, tensile, and flexural properties. However, an optimum fiber content was identified. This study provides valuable insights for designing and applying fiber-reinforced concrete in construction projects, enhancing the durability and resilience of structures. In conclusion, the investigation carries substantial possibilities for improving concrete structure’s performance. By examining mechanical properties of GFRC, the research strives to offer valuable insights capable of improving our knowledge for composite materials in construction engineering.
