In Brazil, the majority of construction and demolition waste materials (CDW) is sent to waste dumps or landfill sites. Having low cost applications in mind, this work has the purpose of investigating the effect of the incorporation of fired ceramic rubble reclaimed from CDW obtained directly from the building construction industry on the final properties of compressed earth blocks, which are especially interesting in low-income and marginalized communities. To this aim, clay-based mixtures containing up to 5 wt.% of ceramic rubble were prepared. Lime and cement were added as binders (6, 8, 10 and 12 wt.%). Cylindrical test pieces were produced by uniaxial compression and left to harden at ambient conditions for 7, 28 and 56 days. The hardened specimens were characterized in terms of microstructure (SEM), compressive strength, water absorption and wear resistance. The results obtained in physical and mechanical evaluation tests demonstrated that small contents of ceramic rubble from the building construction industry can easily be incorporated into compressed earth blocks without degradation of typical properties, enabling savings in cement addition.

Abstract The construction sector plays a crucial role in the transition to a circular economy and a more sustainable society. With this objective in mind, Flanders – the Dutch speaking part of Belgium – makes use of a traceability procedure for construction and demolition waste in order to guarantee that value can be derived from downstream waste processing activities. This article takes this traceability procedure as a legal case study and examines if the use of blockchain technology could lead to even stronger supply chains, better data management, and, more generally, a smoother transition to circular practices in the construction sector.

The abundant availability of demolition waste from construction industry is leading towards a significant problem of disposal, land and air pollution. The natural aggregate resources are also depleting due to development of construction activities. An attempt is made in this study to convert this waste into wealth by substituting the recycled brick from demolition waste to granite aggregate in production of the concrete. The granite aggregate (GA) is replaced with recycled brick aggregate (RBA) by 25% of its weight to produce M15 and M20 grades of concrete. The granite aggregate concrete (GAC) and recycled brick aggregate concrete (RBAC) were subjected to different temperatures between 100 to 1000oC for a duration of 3 hours and the mechanical properties such as compressive strength and flexural strength were examined to assess its fire performance. The response of RBAC is better than GAC at each temperature. The study revealed that the residual strength increases with the increase in grade of concrete at all temperatures.

The problems arising from construction and demolition waste have always been in our country. The civil construction industry is the sector that generates the most waste that impacts society and is the one that consumes the most raw materials. As a result, it is necessary and extremely important that there is a sustainable management of construction waste. The irregular dispositions of these residues cause many negative impacts to the environment, since they are often thrown in vacant lots, permanent preservation areas, roads and public places, harming the quality of life of the population. Recycling can generate a significant economic advantage in relation to the final destination both in regular deposits and mainly in relation to the irregular ones that cause so much damage to the environment. This study sought to collect information on the current situation on construction waste. And in order to be developed, the present work used bibliographic research in books, specialized magazines, periodicals, and electronic media. Concluding in the final considerations, in which vital points of the research are presented followed by the stimulations the continuity of the studies and the reflections on the generation of solid residues in the civil construction.

When recycled aggregates are used appropriately, it is possible to obtain good quality, economic and environmentally friendly building materials. The emergence in recent years of the use of recycled materials in the construction industry, specifically in the production of concrete, has met with varying degrees of success due to the barriers that the market for recycled products has still to overcome. Scientific studies have focused on the good properties presented by the coarse fraction of construction and demolition waste (CDW), leading to the formulation of various international recommendations which, although still insufficient, provide a stimulus to the use of recycled aggregates in concrete.

China is experiencing a large scale of building construction, attracting great attention paid to debris generated by frequent construction and demolition activities for its cost inefficiency and environmental pollution. It is of great importance to better understand the magnitude and composition of the waste stream when developing rules, policies and strategies to manage this segment of the solid waste. In this study, after clarifying the definition of construction and demolition (C&D) waste according to its complex composition and diverse sources, approaches quantifying C&D waste to meet different requirements were summarized, and a simple weight-per-construction-area was employed to make an approximate estimation. Based on the main causes and status quo of C&D waste management, measures to reduce C&D waste were proposed to realize a sustainable construction industry, which include improving environmental awareness, strengthening the establishment of policy system and company waste management system, and reinforcing research and study work. This study also adds to the knowledge on research trend of C&D waste in China.

Use Of Resources

The construction industry is one of the world´s largest consumers of resources (sand, building materials) and produces significant amounts of waste. Simultaneously it is one of the least digitalized industries. With increasing levels of urbanization, scarceness of resources and lack of landfills, the policy of circular economy (CE) is becoming increasingly important in the construction industry. The European Union is obliging material recovery of construction and demolition waste to a minimum of 70% by weight by 2020 for all new construction projects. Simultaneously, digitalization in construction is one of the major goals in the EU digitalization action plan. We thereby hypothesize that digital technologies have significant potential to support CE in Architecture, Engineering and Construction (AEC) in multiple ways – for assessment of resources as well as for the prediction and optimization of upcoming waste and recycling masses. Based on our conducted and ongoing research projects - BIMaterial: Process-Design for a BIM-based Material Passport; SCI_BIM: Scanning and data capturing for the Integrated Resources and Energy Assessment using Building Information Modeling; and finally a Case Study reviewing digital tools and processes within a large design and planning company (DPC) - we assess to which degree and to what purpose digital technologies are used, and define the potentials and challenges for the realization of CE objectives in the construction industry. Based on the conducted assessment, we propose a framework for a Digital Platform for Circular Economy (DEEP), integrating various stakeholders and data repositories on the external (inter)-firm and internal (intra)-firm level, using open interfaces. Such a platform for the AEC aims to optimize the use of resources in the circular economy – from cradle to grave, foster mutual learning and coordination, and finally generate added value along the life cycle of a building project.
