“…The widespread application of concrete in construction can be attributed to its manifold advantages, encompassing high mechanical strength, ease of production and shaping, and comparatively economical costs [1][2][3][4][5]. However, concrete is often characterized as a brittle material with limited deformability and a tendency to rapidly propagate cracks under tensile stresses.…”

“…Sisal fiber, derived from the Agave Sisalana plant and recognized as one of the most extensively researched natural fibers for cement-based composites, distinguishes itself through widespread availability and exceptional mechanical properties. This makes it a prime choice among available natural fibers for applications in the construction industry [5,12]. Sisal fiber stands out not only for its cost-effectiveness but also for its elevated tensile strength, abrasion resistance, and toughness.…”

The rapid growth of Natural Fiber Laminate (NFL) innovation is a direct response to environmental challenges, positioning these materials as superior alternatives to synthetic fiber composites. This paper delved into the outcomes of an extensive experimental study investigating the influence of sisal fiber (SLF), banana fiber (BF), and glass fiber (GF) on the mechanical and microstructural characteristics of concrete. The water absorption curves were established for sisal fiber concrete (SLFC), banana fiber concrete (BFC), and glass fiber concrete (GFC). Furthermore, Scanning Electron Microscope (SEM) observations were conducted to perform microanalysis and failure analysis of the tested specimens. The results revealed significant improvements in the concrete containing fibers compared to its counterpart in fiber-free concrete. For mixtures with a water-to-binder (W/B) ratio of 0.3, the most optimal mix (GF-30-135) showed improvements in compressive strength, flexural strength, and splitting tensile strengths by 4.13%, 8.93%, and 10.10%, respectively. On the other hand, for W/B of 0.4, mix GF-30-135 showed improvements of 5.05%, 8.55%, and 11.60%, respectively. Furthermore, as the fiber content increased, microscopic analyses revealed a weakening of the bond between the fibers and the rest of the matrix, contributing to the deterioration of the mechanical properties.

This study presents the potential of modi ed Palm Kernel Shell (MPKS) particles in the production of blocks as an alternative building material using cement or clay as binders. Several studies on Palm Kernel Shell (PKS) as a blend with other natural bres/ llers found that due to its hydrophilic nature, it has low physical and mechanical capabilities in comparison to MPKS, making it less compatible with any polymeric matrix. Experimental tests were conducted to determine the physicomechanical attributes of MPKS/Cement and MPKS/Clay blocks, including characterization of the cement and clay using Atomic Absorption Spectroscopy (AAS), as well as moisture content, water absorption, hardness, apparent porosity, bulk density, compressive strength, and ake. The morphology of the samples was determined using Scanning Electron Microscope (SEM). Results show that MPKS/Cement block samples exhibit superior physicomechanical and morphological properties compared to MPKS/Clay. The MPKS/Cement block sample moisture content ranged between 4.76 -9.94%. The 80/20 MPKS/Cement sample recorded the most water absorption at 49.5%, and a microhardness value of 82.3 Hv for the 20/80 sample. The MPKS/Clay samples showed higher values of apparent porosity but recorded the least bulk density in the 80/20 samples. The 20/80 MPKS/Cement and MPKS/Clay samples showed the best compressive strength at 63.72 and 50.3 N/mm 2 respectively, while 80/20 for both cement and clay displayed very weak compressive strengths. The ratio 20/80 of MPKS/Cement is observed to be the optimum ratio where better properties of the composites were obtained. For the structure industry's longterm viability, MPKS' superior mechanical properties as an aggregate in block manufacturing make it an asset material as an alternative for some high-cost construction resources such as sand.
