There have been considerable developments in Merseyside and generally in the North West of England over the last fifteen years with regards to the commercialisation of recycled demolition aggregate. Merseyside, and more specifically Liverpool is an urban region that has undergone regeneration in the last fifteen years. This required the...

In many developing countries, the rapid growth of town and cities has generated a rising levels of waste and illegal dumps have become a serious issue. The booming construction industry in Mongolia has resulted in the production of massive amounts of CDW which is one of the largest waste streams. In Ulaanbaatar (UB) and other cities in Mongolia,...

The framework of the research presented in the paper is a project oriented to promote the use of construction and demolition waste (CDW) as a new resource for constructing sustainable and very low-energy buildings. Intensive research activities have been carried out in application of recycled concrete and recycled brick as a replacement of...

The main goal of this paper is to identify barriers and opportunities for creating the circular business models in the EU C&DW sector. Having in mind this fact, author of the paper describes market, social, governance and regulatory failures which may limit opportunities for achieving market success in the EU C&DW sector. The presentation will...

The recycled concrete aggregates (RCA) produced by the demolition of old buildings seem to be an option in order to construct new buildings and to preserve the environment by the reusing of inert materials, reducing the resort to the natural materials and the disposal in landfills. Numerous countries are multiplying studies concerning this...

Construction and demolition waste stream has generated news materials that may be reintroduced into new concrete, e.g. as recycled aggregates. The specific feature of recycled concrete aggregates (RCA) is the presence of hardened mortars influencing their behaviour. This study aims to distinguish processes that allow the complete separation and...

Production of waste materials, via industrial and human activities, creates big environmental and economic problems but also opportunities to recover valuable resources. EU28 currently generates 461 million tons per year of ever more complex Construction and Demolition Waste (CDW) with average recycling rates of around 46%. There is still a...

Abstract only - The existing construction waste recycling technologies and standards have been long applied in construction and demolition (C&D) waste recycling, mainly focused on the production and use of coarse recycled aggregates. Very few papers and process focus on the production of recycled sand although some previous results show that...

The C2CA concrete recycling process consists of a combination of smart demolition, gentle grinding of the crushed concrete in an autogenous mill, and a novel dry classification technology called ADR to remove the fines. The` main factors in the C2CA process which influence the properties of Recycled Aggregates or Recycled Aggregate Concrete (RAC...

Large amounts of construction and demolition wastes (C&DW) especially concrete wastes are generated annually and will increase in the future. Until now, only a small fraction of concrete wastes is re-used as recycled concrete aggregates (RCA) in the manufacture of concrete. In this paper, the feasibility of using RCA obtained from old concrete...

At present, heterogeneous and fine-grained masonry rubble can only be recycled at very low level. To overcome this limitation, the material was employed as feedstock for the production of lightweight aggregates in a thermal process similar to that used in the manufacture of expanded clay and expanded slate. To that end, the fundamental...

Abstract only. - This report firstly presents the current state of construction and demolition (C&D) waste generation in PR China. It is found that the composition of C&D waste in mainland China is much different from other countries, leading to some difficult on the aspect of waste concrete recycling. As a result, in China, some reclamation...

France is currently producing about 17 Mt/year of demolished concrete, most of this material being used in road subbase courses or embankments. However, this flow should increase in the near future, although less and less new roads are to be built. Another 20 Mt of mixed demolition materials, a good part of it being concrete or natural rock is...

The improvement of inline mixer measurements is imposed in a growing concrete industry employing increasingly complex manufacturing processes and materials. Improper mixing, water content estimation and fresh properties control are one of the most important concerns of concrete manufacturers. These problems have increased in recent decades due...

Although there has been extensive research and several demonstration projects in Belgium and abroad, the use of recycled aggregates in concrete is still limited in practice. Several barriers were identified: lack of practical experience, limiting standards and the need for specific quality assurance. The paper describes recent developments in...

This paper investigates the water content of pre-saturated recycled concrete aggregates (RCA) that has a diameter of 1-4 mm called recycled sand (RS), in order to determine the degree of saturation of the RS. It also puts forward the effects of the saturation state of the RS on the mechanical properties. For this matter, experiments were...

Recycled concrete aggregates (RCA) have been widely used as concrete aggregates in construction. This is due to economic and environmental benefits of using RCA in concrete. Unlike natural aggregate (NA), the use of RCA in concrete seems not promising to the users implementing it, especially in structural purposes. The RCA concrete is reported...

The study presented here aims to develop the use of recycled aggregate issued of concrete in total replacement of natural materials (sand and gravel). In regard to natural aggregates, recycled concrete aggregates (RCA) contain mortar that influences theirs properties and those of concrete in which they are used (RCA). The objective of this work...

In a context of incitation to the waste recovery as recycled aggregates to be re-introduced into new concrete, this paper aims to compare the environmental impacts related to the composition of concrete to ones due to the transportation of the recycled aggregates, issued from demolition wastes, by implementing a life cycle assessment (LCA). This...

The concept of circular economy envisages that the highest utility and value of a material can be achieved through proper management along its all life cycle. Therefore reducing waste, through increased reuse and recycling, is a major driver to close the loop. Within this framework, construction and demolition waste, which constitutes up to 30%...
