Life cycle analysis and performance assessment of bagasse ash-glass powder used concrete

Sustainable cement production is a focus to achieve environmental sustainability in the construction sector. Despite earlier research studies on the individual use of sugarcane bagasse ash and waste glass powder in concrete, studies on their combined utilisation in ternary cement are exceedingly minimal, particularly research on the life cycle is extremely limited. Thus, this study conducts the strength, durability and life cycle assessment of binary and ternary blended concrete. Binary concrete was prepared with bagasse ash (10%, 20%, 30%). Glass powder (5%–15%) was used along with bagasse ash to cast ternary concrete. Besides, environmental impact assessment was conducted using the cradle-to-grave approach. Results show that 10% bagasse ash and 5% glass powder-used ternary concrete exhibited higher compressive strength and better resistance to chloride ingress than control and binary concrete. Moreover, control concrete exhibited 6%, 10% and 8% higher impacts on the ecosystem, human health and resource depletion, respectively, compared to binary concrete with optimum dosage of bagasse ash (10%). Furthermore, the ternary concrete resulted in lower environmental impacts than binary concrete. Overall, the combined use of bagasse ash and waste glass powder-used ternary concrete signifies the potential as a sustainable alternative to conventional cement.
