Effect of High Performance on Glass Fibre-Reinforced Concrete Beams

Abstract

Concrete is one of the best building materials because it is cheap and easy to work with. It has some flaws, like being very brittle, having a high heat of hydration, having a low tensile strength, and being hard to crack. High-Performance Fibre-reinforced Concrete (HPFRC) is a relatively new building material that is made of a high-performance concrete matrix and fibre reinforcement. This experiment looks at how flexible HPFRC is when it has Silica Fume (SF) and Glass Fibres (GF) in the same matrix, which makes the concrete stronger and lasts longer. High-performance Concrete (HPC) needs fibres to improve its mechanical properties, especially its tensile and flexural strengths. The compressive strength and flexural strength tests were used to figure out what the mechanical properties were. In this particular experiment, HPC was produced using everyday components such as cement, fine aggregate, coarse aggregate, water, and mineral admixtures such as Silica Fume (SF). As a high amount of cement replacement, approximately 10% of SF was also added. The compressive and flexural strengths both improved as a result of this.
