Sustainability in Buildings: New Trends in the Management of Construction and Demolition Waste, 2nd Volume

Topic Information

Dear Colleagues,

After the success of our first initiative, we encourage you to contribute to the Topic "Sustainability in Buildings: New Trends in the Management of Construction and Demolition Waste, 2nd Volume". This initiative aims to collect works related to the use of new sustainable construction materials, new rehabilitation and conservation techniques, new advances in the recycling of materials for their application in building, as well as new techniques and measurement processes that favour the development of sustainable construction. Contributions related to the proposed lines of research will be valued and that allow for the improvement of the management of construction and demolition waste for its application in the building sector. The main idea is to promote the development of new construction materials and new measurement techniques from different perspectives such as sustainability, materials science, measurement techniques and the development of new sensors and data collection equipment. The focus is on the rehabilitation and conservation of built heritage in order to move towards the development of sustainable cities. In addition, there is also room for other contributions related to construction, which is in line with the scope of the Sustainable Development Goals included in the 2030 agenda. Therefore, this Topic can complement existing literature on construction and demolition waste management from a multidisciplinary perspective that encourages the exchange of ideas and views. For this reason, we encourage all researchers working in areas of knowledge related to building materials, retrofitting, sustainability and energy efficiency to submit their research.

The use of cemented Aeolian sand-fly ash backfill (CAFB) material to fill the mining area to improve the surface subsidence damage caused by underground coal mining is in the development stage. Their performance with large overflow water and strength loss is not well understood. Few research has been conducted to understand the effects of aeolian sand and coal gangue on the rheological properties of CAFB with plasticizers. Therefore, this study aims to investigate the effects of a plasticizer on the rheological properties, specifically yield stress and viscosity, of CAFB prepared with aeolian sand and coal gangue. CAFB mixes containing 0%, 0.05%, and 0.1% plasticizers were prepared, and yield stress and viscosity were determined at different intervals. Additional tests, such as thermal analysis and zeta potential analysis, were also conducted. It was found that the rheological properties of CAFB are the comprehensive manifestation of the composite characteristics of various models. Reasonable particle size distribution and less plasticizer can ensure the stability of the slurry structure and reduce the slurry settlement and the risk of pipe blocking. The findings of this study will be beneficial in the design and production of CAFB material. Full article

The building sector is facing the challenge of transitioning to a more industrialized construction approach and is thus promoting the development of new materials that enable the production of lighter prefabricated products with enhanced thermal performance. This study conducts the physicochemical and mechanical characterization of a new plaster material intended for application in the building sector. The plaster material developed contains potassium polyacrylate and perlite in its composition and has been reinforced with wood, glass and polypropylene fibers to improve its physical and mechanical properties. The results demonstrate that the combined incorporation of potassium polyacrylate and expanded perlite leads to a decrease in density and thermal conductivity by 10.5% and 47%, respectively, compared to traditional plasters. In addition, the incorporation of reinforcement fibers in the plaster matrix, particularly glass fiber, improves the mechanical strength of the new material. The plaster composite developed for this research offers lightweight characteristics and improves the energy efficiency of the construction systems into which it can be integrated and is designed for use in prefabricated panels and plates especially. This progress represents a step towards more efficient industrialized construction. Full article

Cement mortars are commonly used in building works for the execution of enclosures and exterior rehabilitation of facades. The incorporation of plant-based additives enables the development of ecofriendly construction materials. In this work, a physical and mechanical characterisation of cement mortars with the incorporation of hemp in three morphologies (fibre, powder and pellet) was conducted. The results show how the additions of hemp powder and pellets with a partial replacement of natural aggregate reduce the final density of cement mortars and their thermal conductivity by more than 16% and 19%, respectively. On the other hand, the addition of hemp fibres reduces shrinkage during the setting of cement mortars, improving their flexural strength and increasing their durability. For this reason, it is possible to recommend the use of these mortars with the addition of natural hemp fibres without prior surface treatment to improve the physical-mechanical properties of these construction materials and extend their application field as ecofriendly materials for masonry work.
