Microbial induced calcium carbonate precipitation (MICP) technology has been successfully used to enhance the properties of recycled concrete aggregates. However, the complex source and varied physical and chemical properties of recycled aggregates may have influence on the modification efficiency since microbes are often sensitive to the...

Recycled aggregate concrete is emphasized more and more nowadays due to its importance towards the construction industry and general welfare of our planet. Being such a significant feature with regard to universal sustainable development, every aspect of its properties should be evaluated, examined and optimized so that there is a well-known,...

In the Netherlands, yearly 33 Mton new concrete (roughly 15 billion m3) is producewhile 12 Mton concrete waste becomes available. Recycling of the yearly 12 Mton concrete waste results in roughly 7 Mton coarse recycled concrete aggregate (CRCA) and 5 Mton fine recycled concrete aggregates (fRCA). Currently, fRCA is not used in structural...

Each year a large amount of construction and demolition waste (CDW) is generated in the European Union. For sustainability development the CDW is recycled and re-used. To promote the use of CDW, recycled aggregates from CDW were incorporated in alkali-activated concrete (AAC), which mainly consisted of secondary materials or industrial by...

This study focuses on formulating the most sustainable concrete by incorporating recycled concrete aggregates and other products retrieved from construction and demolition (C&D) activities. Both recycled coarse aggregates (RCA) and recycled fine aggregates (RFA) are firstly used to fully replace the natural coarse and fine aggregates in...

Currently, natural resources are consumed at an alarming rate than their production (United Nations Environment Programme, 2014). This imposes unprecedented pressure on the environment. The problem seems to get worse with the present increase in population and demand for infrastructures. To alleviate these and other related problems, a circular...

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...

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 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...

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...

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...

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...

According to the European Commission website, construction and demolition waste (CDW - consisting of materials such as concrete, bricks, gypsum, wood, glass, metals, asbestos, excavated soil…) accounts for approximately 25% - 30% of all waste generated in the EU. To move towards a recycling society, various policies have been launched by...

Construction and Demolition Waste (CDW) raises an environmental problem due both to the lack of prevention in their production process and little use of recycled material. In order to improve this situation, over the last years the new legislation on the CDW has entered into force, fostering the recovery of waste at its end-of-life and...

Research on construction and demolition waste (CDW) has been identified by the European Commission as a priority due to large volumes generated and high potential for reuse and recycling. Around 750 million tons of CDW are generated yearly in Europe, accounting for 25%-30% of the total waste. The average recovery rate for EU27 is below 50%. RE4 ...
