Commercialization of Hybrid Eco-Concrete Incorporating Shell Powder and Re

Abstract— The construction sector is currently facing increasing pressure to adopt low-carbon materials while providing graduates with industry-relevant competencies. This study also presents a draft conference paper on the potential commercialization of hybrid eco-concrete. It combines where shell powder and recycled plastic aggregates are used in civil engineering education in Technical and Vocational Education and Training (TVET). The paper also combines a quantitative experimental type assessment with a techno-entrepreneurial perspective to position the material not only as a laboratory innovation. It is also as a potentially market-oriented educational product. Seven concrete mixtures were considered here. They consisted of one control mixture while six hybrid mixtures with shell powder used as partial cement substitute and recycled plastic used as partial fine aggregate substitute. Workability values were also assessed using slump values. While mechanical performance was also assessed through compressive strength at 7, 14, and 28 days. The synthesized data set shows that the mixture containing 10% shell powder and 5% recycled plastic aggregate achieved the highest 28-day compressive strength of 31.5 MPa. It exceeded the control mixture. The slump value increased progressively with higher plastic content. It showed better workability, but it also tended towards a reduction in strength when plastic substitution became excessive. From an educational and commercialization perspective, the study findings show that hybrid eco-concrete. It can also serve as a practical innovation platform in TVET. Here it integrates sustainable materials, laboratory validation, entrepreneurial exposure and product-oriented thinking. This study also contributes a structured basis for linking sustainable building materials with commercialization pathways in TVET civil engineering education.
