“…Concrete strength assessment is crucial to eco-friendly infrastructural buildout, and compressive strength is the principal index as it determines the quality of construction works [1][2][3][4][5]. This study is imperative to circumvent the tragedies of structural failure emanating from poor concrete properties.…”

 Potato starch was adopted as a natural admixture in concrete.  Mix design ratios were varied with different percentage fractions of potato starch dosage.  The effect of potato starch admixture on the fresh and hardened concrete properties was investigated.  The optimum percentage of potato starch content for all mixes was stipulated.The urgency to attenuate techno-economic and ecological threats constituted by chemical admixtures has necessitated the adoption of feasible natural admixtures.The chemical interaction of admixtures with concrete ingredients affects concrete's plastic and hardened structure. The impact of concrete properties on construction works is of great concern to engineers as it plays a vital role towards viable infrastructural development. This study focused on developing an ecofriendly, sustainable structural concrete using potato starch (PS) as an admixture. PS has been included to in concrete in discrete percentages (0%, 0.4%, 0.8%, 1.2%, 1.6%, 2.0%) of cement weight employing mix ratios of 1: 1.5: 2, 1:2:4, 1:3:6 and water-cement ratio of 0.6. This study evaluates the effect of PSadmixture on concrete properties in the plastic state (setting time and workability) and at the hardened state (compressive strength) at 7, 21, 28, 56, and 90 days of curing. Potato starch (PS) admixture showed higher compressive strengths in concrete mixes with lower ratios (1:2:4 and 1:3:6). The strength test results for the 1:1.5:2, 1:2:4 and 1:3:6 mix ratios show a maximum strength of 32.77 N/mm 2 , 35.12 N/mm 2 and 38.97 N/mm 2 respectively for 28 curing days, at 1.2% PS addition, after which there was a strength-reduction. Rise A rise in the percentage inclusion of PS boosts the setting-time of cement paste and compressive strength. An optimal-percentage of 1.2% PS by cement-weight is advised for reliable concrete strength performance. Utilization of PS in concrete is recommended and should be embraced, considering its low-cost, availability, environmental amicability, and ability to enhance structural durability.

As efforts intensify to address the environmental impact of agricultural waste, the valorization of Manihot esculenta peel (MEP) for sustainable engineering applications presents a unique opportunity to repurpose this class of agricultural waste to achieve environmental sustainability development goals while promoting socio-economic development of this pollutant. The inherent properties of MEP, such as its richness in carbohydrates and cellulose, make it a useful raw material for producing biofuels, bioethanols, biocomposites, and other sustainable engineering materials. Its resilience to adverse environmental conditions also makes MEP well-suited for cultivation in diverse agroecological settings, further enhancing its appeal as a sustainable resource. While existing review articles provide valuable insights into Manihot esculenta peel utilization across various industries, they often overlook the comprehensive valorization of Manihot esculenta for sustainable engineering applications, creating a notable knowledge gap. Through a systematic examination of innovative approaches documented in the literature, this research seeks to bridge this gap by elucidating strategies for repurposing cassava waste into valuable engineering materials to mitigate environmental pollution and promote sustainable resource utilization. By synthesizing existing research and identifying key research gaps, this study advances the understanding of Manihot esculenta peel’s potential as a sustainable material and facilitates the transition toward greener engineering practices.
