Comparative Analysis on Load-deformation Behavior of RC Slabs Incorporating Nano-SiO₂ and Coconut Fibers

For modern building materials, improving the structural performance of reinforced concrete (RC) slabs is essential, especially when it comes to maximizing strength, durability, and sustainability. The load-deformation properties of RC slabs with Nano-SiO₂ and coconut fibers are examined in this work. By combining these materials, slabs' mechanical qualities, self-weight, and structural efficiency are intended to be improved. Because of its exceptional strength and self-cleaning qualities, Nano-SiO₂ strengthens the concrete matrix, increasing its resilience to environmental deterioration and durability. As a natural reinforcement, coconut fibers improve flexural performance, toughness, and fracture resistance. Modified RC slabs are cast and tested in this research to assess their overall structural integrity, deflection behavior, and load-bearing capability. Experimental testing, such as load versus deflection analysis, is carried out to compare the slabs' deformation characteristics. The findings show that in comparison to traditional slabs, slabs containing Nano-SiO₂ and coconut fibers have better load resistance, less breaking, and increased ductility. Fiber reinforcement also increases overall structural efficiency by lowering dead weight, which may enable wider spans and lower foundation loads. The results of this study provide essential light on the advantages of incorporating coconut fibers and Nano-SiO₂ into RC slabs. These materials offer a novel approach to lightweight, high-performance slab systems appropriate for contemporary building applications by improving mechanical qualities and sustainability. The research emphasizes how concrete solutions based on cutting-edge and environmentally friendly materials may increase the lifetime and effectiveness of RC constructions.
