Special Issue Information

Dear colleagues:

One of the main challenges facing the construction sector today is making rational use of resources in modern societies compatible with the development of productive activity based on the criteria of circular economy and energy efficiency. Today, the few waste collection points coupled with the difficulty in separating materials as heterogeneous as those generated in construction and demolition works (CDW) makes it very difficult to recycle these materials and opens a line leading and relevant research. Thus, within Horizon 2030, we are faced with the challenge of recycling and reusing a large amount of waste generated in industry, a clear example of this being the milling, separation, cleaning, treatment, and reuse of CDWs for the generation of aggregates and their reincorporation into construction work. For this reason, I encourage you to send your contributions examining how to achieve sustainable construction, and especially your studies on the use and application of aggregates from construction and demolition waste to the production of construction materials. The list of topics includes (but is not strictly limited to):

  • Treatment of construction and demolition waste;
  • Applications of recycled aggregates to construction;       
  • Mortars and concretes made with recycled aggregate;     
  • Circular economy applied to the building;    
  • Reverse logistics applied to the construction sector;  
  • Clean production in the construction sector;       
  • Models and simulations for efficient coatings;   
  • Precast construction with CDW incorporation;  
  • Management of construction works to achieve the objectives for sustainable development;
  • New eco-friendly construction materials;     
  • Technology innovation in sustainable building.

The construction sector is one of the main consumers of raw materials and generates a high volume of waste within the European Union. The search for new materials that are more sustainable and respectful of the environment has become a challenge for countries with a high degree of industrialization. In this work, a study of the most relevant properties of masonry mortars made with recycled aggregates and reinforced with synthetic fibers was carried out. Three types of aggregates were used—natural, concrete recycling and ceramic recycling—and two types of reinforcing fibers: polypropylene and polyolefin. In this way, various tests of physical-mechanical characterization and a statistical analysis of the results were carried out. It has been shown that the mortars made from aggregate recycled concrete and reinforced with polypropylene fiber are the ones with the best properties for application in the construction sector, although without improving the properties of traditional mortars made from natural aggregate and without fibers.

The use of waste materials in road construction is becoming widely spread due to economic and environmental needs. Construction and demolition waste materials and mining residues have been studied for a long time. However, the use of fine materials, mainly from mine tailing and mining residue, is still complex, as they can be used as inert materials into the mix or can become a reactive agent in geopolymer mixes. In the present paper, an experimental application of basalt powder is proposed in the geopolymerisation reaction to produce artificial aggregates. In order to understand the input and output variables’ interactions used in the mix design, a statistical method called Design of Experiments was applied. With this design approach, it was possible to optimize the mix design of the experimental geopolymer mortars. The study evaluated several mixes with respect to their workability, compressive strength, and success rate of aggregates production. Finally, a model for predicting compressive strength is proposed and evaluated. Full article

The construction sector is responsible for one third of the total wastes produced in the EU. Finding solutions for the reuse or recycling of these wastes is one of the major environmental concerns of modern times. The replacement of sand or cement in specific construction materials, such as concrete or mortars, is a possible solution for these wastes’ management. By using construction and demolition wastes in construction materials, namely on buildings, the cycle of circular economy is closed, increasing the life cycle of the wastes in the same sector. In this research, a reduction of cement content in rendering mortars is analysed. This reduction is achieved by a decrease of the cement/aggregate ratio simultaneously with the incorporation of very fine recycled aggregate from construction and demolition waste. Two recycled aggregates were studied: recycled concrete aggregate (RCA) and mixed recycled aggregate (MRA). The fresh and hardened state properties of the mortars were analysed. Several tests were carried out to evaluate the mortars’ performance, such as mechanical strength tests, water absorption tests, drying tests and shrinkage. It was noticed that the incorporation of RCA led to a better behaviour than in the reference mortar, in terms of mechanical strengths and protection against water. Full article
