2017-11-23 Recycled aggregates Recycled aggregates are those derived from reprocessing materials previously used in construction, e.g. crushed concrete or masonry from construction and demolition waste material. Secondary aggregates By-products of industrial processes that can be processed to produce secondary aggregates.
2007-6-4 As a part of the Norwegian research project RESIBA, a certification scheme for recycled aggregate has been establised. RESIBA was a 3-yearly project supported by the Norwegian EcoBuild and was finalized spring 2002. The aim of the project as a whole was to formulate
Recycled masonry aggregate (RMA): aggregate derived from masonry rubble such as ceramics bricks and sand–lime bricks. Mixed recycled aggregate (MRA): aggregate consisting mainly of RCA and RMA.

2021-8-5 There are two methods of producing recycled aggregate: at the site of the source the benefits of this include saving on transport costs and the environmental benefits of reducing lorry movements; in a central plant; Examples of recycled aggregate include recycled concrete from construction and demolition waste material and railway ballast.
2013-3-26 Recycled aggregate concrete (RAC) may be recognised as a type of green material which can help conserve the natural resource, decrease energy consumption, reduce landfill requirements and save construction cost . However, some widely recognised drawbacks of RAC, such as low strength, low elastic modulus, high creep and shrinkage, have limited its development and structural applications.
2021-8-1 Using recycled materials is a new method to manufacture reinforced concrete (RC) elements in civil engineering. Recycled materials come from different sources such as old buildings demolition, glass waste, stone powder, among others. These materials could be partially or totally replaced cement and aggregates.
Accelerated carbonation for recycled concrete aggregate (RCA) was one of the effective and economic solutions for improving the quality of RCA and its concrete products. Previously, a fast wet carbonation method was developed and proved to be effective for property enhancement of the coarse fraction of RCA by transforming the carbonation reaction from a gas-solid phase to a liquid-solid phase.

2018-5-1 Although the researches on recycled aggregate concrete (RAC) has been going on for nearly 70 years,the use of RA in concrete structures is still limited due to its long-term durability concerns. With the decrease of natural aggregate resources and the increase of waste concrete generation, RAC has become a hot research topic around the world.
2013-3-1 One of the most unknown aspects of recycled aggregate concretes is related to their durability in aggressive environments. Also most of the results found in the literature are not comparable due to the heterogeneity of the recycled aggregates, water/cement ratios and types of cement used.
The durability of the concretes made with recycled aggregate is worse due to the intrinsic porosity of them. These differences decrease for low w/c ratios, as in this case the most influential factor is the low porosity obtained in the new improved cement paste. Considering the mechanical properties, the influence of the recycled aggregate is worse for the high w/c ratios.
Recycled aggregate concrete (RAC) becomes a great concern for massive natural resoure comsumption and a huge con-struction waste. Many researchers have carried out numerous investigations on the durability of RAC. The purpose of this paper is to summarize the achievements and share them with researchers involved in the study on RAC. In this pa-

Unfortunately, although the behavior of recycled aggregate concrete (RAC) has been widely investigated in the last few years, there are still knowledge gaps to fill on various aspects of the RAC performance, such as its durability in extreme conditions. The present study deals
2008-1-1 This suggests that recycled aggregate in concrete may impose a high risk to the durability of concrete structures in terms of chloride-induced corrosion of steel. Chloride ions will enter the concrete cover containing recycled aggregate more easily due to a higher rate of permeability altogether with water sorption, and subsequently reach the depth of the steel faster.
2018-2-28 Meanwhile, a lot of studies have been conducted on the durability of RAC,,. Most of the results showed that the durability of RAC is generally lower than that of natural aggregate concrete (NAC), and it decreases with the increase of recycled coarse aggregate (RCA) replacement ratio,,.
2020-11-10 However, the utilization rate of recycled coarse aggregate (RCA) in China is still relatively low. In order to better improve the efficient utilization of waste concrete in the complex environment, the durability resistance of RAC with diverse substitution rates under the coupled action of freezing-thawing (F-T) cycles and chloride attack was investigated in this paper.
2017-8-29 Table 1 Effect of recycled aggregate on concrete properties. Durability Durability of Recycled Aggregate (RA) can be influenced by coarse aggregate replacement ratio, concrete age, w/c ratio, and moisture content; generally, a lower w/c ratio generates a more durable concrete mix.
2015-5-14 This paper discusses the suitability of producing concrete with 100 % recycled aggregate to meet durability and strength requirements for different applications. Aggregate strength, gradation, absorption, specific gravity, shape and texture are some of the physical and mechanical characteristics that contribute to the strength and durability of concrete.
