There has been a significant increase in volume of new clothing sales over the last ten years; indeed it is the fastest growing waste in household waste stream, raising the potential for a similar increase in volume of textile waste dispose in landfill sites and the resultant harm to the environment. As volume of throwaway fashion increases and...

According to the 2008 data, recycling rates in 60 municipalities in Bologna Province vary in a very wide range from 15% to over 60%. In order to promote sustainable practices of resource (in this case, materials) recovery, it is important to identify factors that influence the attitudes and behaviour of citizens in this regard and clarify the...

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...

Construction and demolition activities generate a large quantity of C&D waste. It is estimated that almost 70% of the buildings that are expected to stand in India by 2030 are yet to be built. Hence, C&D waste generation is expected to grow larger in the coming years and managing it would play a vital role in the conservation of natural...

In order to clarify the significance of Los Angeles test when being used with RCAs, three aspects were investigated: the influence of the number of revolutions, the evolution of the full particle size distribution and the distribution of mortar in the fractions after the test. The standard testing procedure for the Los Angeles index requires the...

The European Circular Economy Package focusses on construction and demolition and wants to identify and increase the recovery of valuable materials. A densely populated area such as Flanders, with no space for landfills and hence very high landfill taxes is driven towards recycling and reuse. Flanders is one of the leading regions when it comes...

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...

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...

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...

The use of recycled aggregates in new structural concrete is generally considered as a measure for lowering the environmental impact of concrete. Existing literature considers transport distances and the final performance of the concrete (linked to its composition) as main influencing factors to evaluate the environmental burdens or gains when...

Current concrete recycling consists of crushing waste concrete and use it again as aggregate for new concrete, according to specifications which are based on local regulations in different countries. Construction and demolition waste recycling is generally limited to the use of the coarser fraction as aggregate for new concrete. The quality of...

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...

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 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...

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...

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...

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...

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...
