“…Israel, Pakistan, Spain, Brazil, Italy, Poland, Slovakia, the UK, South Africa, Iraq and Singapore each added just 1% to the total number of publications. Countries like Brazil, which generates a considerable amount of construction and demolition waste (Esguícero et al ., 2021), need to conduct further research to find the best solution for using recycled concrete as the aggregates.…”

PurposeThis study aimed to review various existing methods for improving the quality of recycled concrete aggregates (RCAs) as a possible substitution for natural aggregates (NAs) in concrete. It is vital as the old paste attached to the RCA weakens its structure. It is due to the porous structure of the RCA with cracks, weakening the interfacial transition zone (ITZ) between the RCA and binding material, negatively impacting the concrete's properties. To this end, various methods for reinforcement of the RCA, cleaning the RCA's old paste and enhancing the quality of the RCA-based concrete without RCA modification are studied in terms of environmental effects, cost and technical matters. Furthermore, this research sought to identify gaps in knowledge and future research directions.Design/methodology/approachThe review of the relevant journal papers revealed that various methods exist for improving the properties of RCAs and RCA-based concrete. A decision matrix was developed and implemented for ranking these techniques based on environmental, economic and technical criteria.FindingsThe identified methods for reinforcement of the RCA include accelerated carbonation, bio deposition, soaking in polymer emulsions, soaking in waterproofing admixture, soaking in sodium silicate, soaking in nanoparticles and coating with geopolymer slurry. Moreover, cleaning the RCA's old paste is possible using acid, water, heating, thermal and mechanical treatment, thermo-mechanical and electro-dynamic treatment. Added to these treatment techniques, using RCA in saturated surface dry (SSD) mixing approaches and adding fibres or pozzolana enhance the quality of the RCA-based concrete without RCA modification. The study ranked these techniques based on environmental, economic and technical criteria. Ultimately, adding fibres, pozzolana and coating RCA with geopolymer slurry were introduced as the best techniques based on the nominated criteria.Practical implicationsThe study supported the need for better knowledge regarding the existing treatment techniques for RCA improvement. The outcomes of this research offer an understanding of each RCA enrichment technique's importance in environmental, economic and technical criteria.Originality/valueThe practicality of the RCA treatment techniques is based on economic, environmental and technical specifications for rating the existing treatment techniques.

One of the biggest problems in the construction industry that often generates delays and loss of value in the construction site are the processes related to the management of material transportation. These processes are decisive in collaborating in the search for greater productivity. Lean Construction (LC), together with its tools and techniques, is a methodology that is being implemented in the sector and whose objective is the identification and elimination of waste on-site. The objective of this work is to analyze the impact of implementing the LC methodology in the construction sector focused on the transportation of materials, as well as to verify the other benefits of the methodology. In this systematic literature review (SLR) work, seven online databases were used to search for scientific manuscripts related to the LC methodology and the materials transportation process; after being analyzed and systematized using the prism methodology and the inclusion and exclusion criteria, 54 manuscripts were selected, seeking to answer the research questions. The results indicate that 21 manuscripts state that the benefits provided by the application and execution of LC are fundamental to ensure the execution and success of the project. Also, LC tools and techniques are essential to improve productivity. Also, the analysis shows that the main challenges are lack of management commitment, lack of willingness to change the culture, lack of skills and lack of training. Finally, the importance of management in the building materials supply chain is demonstrated by identifying the drivers and enablers.
