520			_aThe study examines the feasibility of producing concrete paving blocks by substituting ground pili nut shells for a portion of fine particles. Appropriate mix designs for the concrete paving blocks were developed with varying ratios of pili nutshells: 0%, 5%, 10%, 15%, and 20%. The dimensions of the concrete blocks were standardized at 10x20x8 cm. Due to the unavailability of a crushing machine, pili nutshells were manually crushed for use in this research. The primary objective was to evaluate the impact of replacing fine particles with pili nutshells on the concrete paving blocks' physical and mechanical properties, strength, and durability. Various mixed proportions of pulverized pili nutshells and fine aggregates were tested through a series of experiments. The results revealed that incorporating pili nutshells enhanced specific properties of the concrete, including improved compressive strength and increased sustainability. The study suggests the potential application of pili nutshells in other construction materials, such as concrete hollow blocks or fiberboard, as an innovative additive. This research highlights the potential of utilizing agricultural waste, such as pili nutshells, as a sustainable and effective alternative to traditional fine aggregates. It offers a novel solution for concrete paving applications while promoting environmental sustainability. The results of the conducted evaluation indicated a high level of excellence for the prototype, with an overall mean score of 4.53 on the descriptive scale. The study paves the way for future research into using agricultural byproducts in concrete production, contributing to a more sustainable and circular economy. Keywords: agricultural waste, alternative, concrete paving blocks, fine aggregates, partial replacement, pulverized pili nutshell, strength, sustainability
