Conclusion

The investigation into self-compacting concrete (SCC) incorporating varying percentages of silica fume and crumb rubber replacements has provided valuable insights into its mechanical properties and workability. Results indicate that replacing cement with these materials at 5% to 10% levels enhances compressive, tensile, and flexural strengths while maintaining satisfactory workability, crucial for placement and finishing. However, a 15% replacement leads to diminishing strength characteristics. The pozzolanic reaction of silica fume and the reinforcing effect of crumb rubber contribute to these improvements. Additionally, SCC mixes exhibit excellent flow ability, passing ability, and filling ability, meeting code requirements. Optimal replacement levels lie within the 5% to 10% range, balancing strength enhancement and workability improvements, offering an efficient and sustainable solution for concrete production. These findings underscore the potential for using supplementary materials in SCC to enhance performance while addressing sustainability concerns in the construction industry.
