The use of concrete for construction had become very common in developing countries. But concrete is not friendly environment because of it consumes huge quantities of natural materials and production of the cement, which is a major contributor to greenhouse gas emissions and global warming. The aim of this study is to investigate the Sustainable Green Concrete (SGC) which containing biomass aggregate; fly ash and Superplasticizer. Biomass aggregate and fly ash are waste industry products which are environmentally friendly. The study was carried out to identify the chemical properties of biomass aggregate, and to determine the chemical properties and optimum mix design of the Sustainable Green Concrete (SGC). A total of 90 cube samples were casted and compressive strength were tested at the age of 7, 14 and 28 days. The overall results showed that the workability and compressive strength were decreased with the increase of the replacement of natural aggregate with biomass aggregate. Besides that, the workability and compressive strength was increased with the incorporation with the replacement cement by fly ash. The SGC gained highest compressive strength for the concrete mixes of 39.3 N/mm2 with the optimum percentage used of SGC in producing concrete not exceeding 30% biomass aggregate and 6% of fly ash as a partial replacement with natural aggregate and cement respectively. The results obtained and observation made in this study suggested that biomass aggregate and fly ash are successfully used as partial replacement in producing SGC and can perform better strength development.
