The global focus is on utilizing naturally occurring fibers to create high-quality composite materials. Rice straw, often considered waste, has the potential to accelerate research on composite materials, offering eco-friendly alternatives and reduced manufacturing costs through collaborative production using synthetic fiber. This investigation was conducted to examine the mechanical qualities associated with fiber length using hand layup with cold press technique. Composites reinforced with short fibers demonstrated reduced tensile and flexural strength but had slightly higher impact strength and moderate water absorption. Continuous fiber-reinforced composites exhibited greater mechanical performance, maximum tensile stress observed in rice straw carbon hybrid composites. Carbon fabric hybrid composites noticeably increased tensile strength, 315.5 MPa, showing better tensile, flexural properties due to the rigid structure of carbon fiber. Water absorption was modest across all samples, is ecofriendly and sustainable material. Short fiber composites also show an excellent diffusion co-efficient, with a low slope of 0.57, showing the rate of water absorption is minimal. The resilience of these composites was beneficial, rendering them appropriate for maritime applications and interior purposes. The eco-friendly hybrid composite, made from rice straw and glass fibers, is suitable for various applications like furniture, sports, marine, automotive, and food packaging.</div></div>","PeriodicalId":100614,"journal":{"name":"Hybrid Advances","volume":"9 ","pages":"Article 100402"},"PeriodicalIF":0.0,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143419626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the potential of eco-cement produced using agro-waste materials—eggshell powder (ESP) and water hyacinth ash (WHA)—as sustainable alternatives to conventional cement. Three eco-cement samples with varying compositions of ESP and WHA were prepared and characterized using X-ray Fluorescence (XRF), Fourier-Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscopy (SEM). The XRF analysis revealed that all samples contained a high CaO content (&gt;70 %) and sufficient SiO₂ levels to ensure pozzolanic activity. FTIR spectra confirmed the formation of key hydration products, including calcium silicate hydrate (C–S–H) and calcite, indicating successful bonding characteristics. SEM images demonstrated that increasing the WHA content resulted in a denser microstructure with reduced porosity, which is critical for enhancing the material's strength and durability. The results show that eco-cement formulations incorporating 9 % WHA exhibit superior microstructural properties, suggesting their potential for practical applications. By utilizing waste materials, this eco-cement offers a viable solution for reducing the environmental footprint of cement production while promoting sustainable construction practices.
