Capacity to Develop Recycled Aggregate Concrete in South East Asia

The global sustainable construction aimed to minimize the ecological impacts of constructed facilities’ lifetime. In construction, concretes are the major materials utilized in South East Asia. Thus, it makes environmental and economic sense to utilize recycled materials in the production of new concretes for diverse uses. This review indicated that the practical implementations of the recycled aggregate concretes (RAC) in the area is greatly lacking, even though there are reasonable studies on RAC, particularly because of lack awareness and economic viability of such uses at the present period. This research aims to establish an interdisciplinary consortium with researchers, policy makers, practitioners, and social scientists in Southeast Asia to investigate the development of sustainable, durable, cost-effective, green concrete by utilizing recycled aggregates. Concentrating on waste resource recovery, this research presents an integrated modeling method. The approaches track and forecast a variety of values across technical, economic, social, and environmental areas linking these to the material flow and therefore integrating and building upon one-dimensional models like life cycle assessments (LCAs) and material flow analyses (MFAs). Additionally, the analysis of this study supported the recycling of cement for general use in construction, emphasizing the feasibility, reliability, and longevity of a project at the same time. However, the analysis also demonstrated that although there is fair progress on recycled concrete, there is still a severe lack of appropriate development in particular because of the lack of economic sustainability and knowledge of such applications at present. Raw material conservations were recorded; carbon dioxide costs and footprint were also reduced. Considering the RAC economic, technical, and environmental parameters, frameworks were applied for sustainable selections with target compressive strengths as the major goal.
