📄 Abstract（原文）
Abstract. The construction industry is one of the most vicious contributors to global GHG emissions, and the sector has a pivotal role to play in mitigating environmental degradation. This study examines the use of corn cob ash (CCA) as a partial substitute for cement in the production of concrete blocks. The study addresses the urgent need to identify and adopt sustainable alternative materials in the construction industry to mitigate greenhouse gas (GHG) emissions and promote environmental sustainability. CCA was used to partially replace OPC at 0%, 5%, 10%, 15%, and 20% by mass. The EDXRF, mechanical properties, embodied energy, global warming potential, and sustainability index of the composite materials were evaluated for each mix. The study found that the optimum mix of 15% CCA led to a 14.43% reduction in GHG emissions compared to the control sample. The study reveals a complex relationship between compressive strength and carbon footprint in concrete composites. The research provides empirical evidence supporting the valorization of CCA as a viable pozzolan in concrete block production. The adoption of CCA as a partial cement replacement leads to lower embodied energy, enhanced waste management benefits, and a reduced carbon footprint for masonry units.
