Abstract
This study provides an in-depth analysis of the experimental investigation conducted on carbon fiber reinforced GGBS concrete (CFRGC). The primary objective of the research was to evaluate the effects of carbon fibers on various mechanical properties of concrete, with a particular focus on strength parameters. In this study, the carbon fiber content was systematically varied from 0.5% to 1.5% by weight of cement, in increments of 0.5%, to determine the optimal fiber percentage that yields the best performance. The strength properties analyzed include compressive strength, split tensile strength, and flexural strength. For the compressive strength tests, concrete cubes of 150 mm were cast, while for split tensile strength, cylinders with a diameter of 150 mm and a height of 300 mm were used. Flexural strength was evaluated using concrete beams of 100 mm × 100 mm × 500 mm dimensions. All concrete specimens were subjected to a curing process in water for periods of 7 and 28 days before being tested for their respective strengths. In addition to mechanical strength, the workability of the CFRGC was also assessed using the slump cone test. This test provided insights into how the addition of carbon fibers affects the ease of handling and placing the concrete. A thorough comparison of the experimental results between carbon fiber reinforced GGBS concrete and conventional concrete revealed significant improvements in the mechanical properties of the CFRGC, particularly in terms of compressive strength. The inclusion of carbon fibers was found to enhance the material’s ability to resist compressive loads, making it a more robust option for structural applications. Moreover, the study also showed that the addition of carbon fibers positively influenced the split tensile and flexural strengths, indicating an overall improvement in the concrete’s durability and performance. The enhanced mechanical properties of CFRGC suggest its potential use in high-performance structural applications, especially where greater load-bearing capacity, improved crack resistance, and better long-term durability are required.
