Mechanical Performance of Date-Palm-Fiber-Reinforced Concrete Containing Silica Fume

The use of date palm fiber (DPF) as natural in concrete and mortar continues to gain acceptability due its low-cost availability. However, the main disadvantage DPF cement-based composites is that it reduces compressive strength increases porosity composite. Hence, for be efficiently used concrete, negative effects must counteracted. Therefore, this study, silica fume was employed supplementary cementitious material alleviate on concrete. added different dosages 0%, 1%, 2%, 3% by weight binder materials. Silica a cement replacement at 0% 15% (intervals 5%) volume cement. unit weights, mechanical strengths, water absorption, microstructural morphology were all evaluated. concrete’s fresh hardened densities reduced with increment fume. declined ages addition, while flexural splitting tensile strengths improved addition up 2% DPF. Furthermore, absorption escalated an increase content. significantly enhanced dissipation mitigated replacing 10% fume, where densified microstructure refined interfacial transition zone between fibers matrix, hence decreasing enhancing durability.
