Abstract
Massive advancement of the infrastructure sector has caused an unforeseen increase in the demand for cement. To accommodate this need, the world expends 30 billion tonnes of cement concrete every year. The rapid growth of cement manufacturing has raised environmental and health concerns due to significant carbon dioxide emissions, contributing to global warming and climate change. A study suggests using sugar cane ash residue as a large-scale substitute for cement to reduce emissions. Handling waste goods is a cost-effective way to reduce pollution and promote sustainability. The study proposes replacing cement by 0% to 30% with 5% increment Sugarcane Bagasse Ash, with some investigators replacing up to 50%. The study with the incorporating sugarcane bagasse ash to concrete enhances its chemical, mechanical, and physical characteristics, such as its reduced permeability, increased strength, and low heat of hydration. The article examines the creation of high-quality SCBAs, emphasizing the importance of controlled combustion and the optimal cement replacement ratio of 10 to 20% for mechanical and durability properties. Overall study is examined for construction material development and Environmental Sustainability. Bibliometric analysis (keyword Analysis, Country Analysis) is performed through VOS viewer.
