Life Cycle Sustainability Assessment of Recycled Aggregates for New Construction: The Case for Qatar

Abstract

The purpose of this project is analyze the use of recycled waste material management for the purpose of circular economy concept, in addition to adopting the concept of life cycle assessment in order to use it for quantifying the benefits and impacts of construction waste recycling the LCA assessment methodology will be used which consists of goal and scope identification, inventory analysis and impact analysis, the scope of this project is focusing on the base foundation of stadium in Qatar, inventory analysis and impact analysis are dealing with the quantities of both conventional and cyclopean concrete and their impacts of environment and society. There is a comparison of using recycled aggregates such as Cyclopean concrete in construction projects and the Conventional Concrete where a calculation will be done to evaluate both systems based on concrete amounts while taking into consideration the unit price of concrete, steel reinforcement and fuel. the main focus will be on sustainable assessment and using of recycled materials in constructing mainly focusing on aggregate for new construction projects in stadiuml's base foundation. There will be a comparison to measure the advantages of using recycled material in aggregates versus the conventional concrete from environmental and social indicators with around 9 indicators in total , the highlights of using recycled materials helps in; Reduced resource use , material
