“…The construction and building sector is poised for a new rapid growth phase alongside deployments of digital technologies with South East Asian countries set to overtake developed economies [9]. The ingredients to make concretes are in high demand and are thus in short supply as concretes are the favored materials of choice in different performance, forms, and characteristics for the upcoming infrastructures.…”

“…The construction departments are interested in how to finish the constructions with the least cost inputs and resources and the fastest rates. The government should support more generation and utilization of RCAs [9]. Their obligations, expectations, and responsibilities must be properly coordinated.…”

“…The development and establishment of national structures supporting the development of sustainable, durable, cost-effective, green concrete by utilizing recycled aggregates can be reinforced through the execution of three programs, including strengthening the capacity of waste services and other waste management bodies and strengthening the State Services on Waste Control of different states in South East Asia and the Asia Waste Control Agency in implementing trade and border control, specifically import and export regimes [9]. Specifically, these programs aim to support the legal frameworks to support the development of sustainable, durable, cost-effective, green concrete through the utilization of recycled aggregates, coordination and mobilization of recycling activities, and effective monitoring of waste situations in these countries.…”

“…The engineers in charge should ensure proper treatment of waste products generated from such developments, utilize reclaimed concretes, and choose the materials and types of structures that are appropriate for recycling and reuse. From building and construction, the generation of wastes needs to be reduced [9]. The waste generation should also reduce the hazardous effects from the generated waste materials.…”

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.

“…There is a great information potential in the application of this waste in the road construction industry. This will help to reduce the negative effect of the improper disposal of the waste [ 1 , 2 ] and its re-use in transportation which is an integral component of national growth [3] , [4] , [5] .…”

Data on the engineering properties of aluminum dross as a filler in asphalt

et al. 2020

Pavement is the backbone of an effective and efficient transportation system. Data on the use of aluminium dross as filler material in the modification of asphalt for a sustainable pavement was espoused. Aluminium dross which is a solid waste from steel production industry was utilized. Data on the engineering and stability properties of the material in enhancing the strength of the asphalt mix design was espoused. This was achieved by adding the solid waste at 0%, 2.5%, 5%, 7.5%, 10% and 12.5% of aluminium dross to the asphalt concrete sample. Marshall Test was used to determine the stability of aluminium dross in flexible pavement and this was used for the selection of asphalt binder content with a suitable density which satisfies minimum stability and range of flow values using AASHTO specification. The data obtained will be of help to researchers, engineers, road construction workers and environmentalist on the use of this solid waste in the construction of sustainable long-lasting roads for national growth and solid waste reduction.
