Utilization of Construction and Demolition Waste in Concrete Production—A Comprehensive Overview
摘要
The dismantling of antiquated infrastructures has increased in recent years, resulting in a substantial increase in construction and demolition (C&D) waste, which currently accounts for approximately 30% of global solid waste. Environmental challenges are presented by its bulky, weighty nature. Utilizing recycled C&D materials in concrete can preserve resources, reduce solid waste, and decrease water, air pollution, and greenhouse gas emissions, all while maintaining the quality of the concrete. Alternatives such as porcine dung, animal fat and silica fume are investigated in the construction industry due to the limited availability of primary resources and the high costs. This research analyses the recyclability and feasibility of C&D refuse for future construction, as well as the necessity of additional research on material reuse.
