Maximizing Mechanical Performance: An RSM-Based Optimization of Bamboo Fiber and Wood Ash in Concrete

Article Preview

Abstract:

Concrete is the most widely used construction material, but its environmental impact and reliance on finite resources have driven the need for more sustainable solutions. This research paper presents the optimization of bamboo fiber and wood ash as supplementary materials in concrete to enhance its mechanical performance and sustainability. A powerful statistical technique known as Response Surface Methodology was employed to systematically investigate the effects of varying bamboo fiber and wood ash content on the compressive and flexural strengths of concrete. The optimal combination of 0.36% bamboo fiber and 13.43% wood ash resulted in a flexural strength of 3.227 MPa and a compressive strength of 18.444 MPa, demonstrating the significant potential of these sustainable materials to improve concrete's mechanical properties. The findings of this study provide valuable insights for the construction industry, highlighting the feasibility of utilizing bamboo fiber and wood ash to develop more durable and environmentally friendly concrete mixtures that can contribute to a more sustainable built environment.
