Recycled Concrete Aggregates
The crushed concrete aggregate has a faster initial set time than virgin material, is lighter in weight, and simpler to place. When it has the right proportions, it has the same shrinkage properties as other concrete. Recycled concrete aggregate is more economical than using virgin aggregates.

The Contribution of Recycled and Secondary Materials to Total
For the year 2008, we assume that total production of recycled aggregates in GB followed the trend seen in England over 2005-08, resulting in a total production of recycled aggregates of 50.8 million tonnes. To our knowledge, there has been no further information published on recycled aggregates at national level since the WRAP (2010) report.

Recycled concrete fines and aggregates- the composition of various size
material was pre-crushed, using the smart crusher at its maximum opening size, in order to simulate the pre-crushing that recycled concrete is submitted to on a larger scale. After that, the material was smart-crushed, sieved on the 2 mm sieve and larger than 2 mm particles were returned to the crusher, in order to maximize the production of fines.

Construction and demolition waste management in Korea: recycled
Status of recycled aggregate production facility. Recycled aggregates are obtained by crushing concrete waste in C&D waste. Unlike natural aggregates, the recycled aggregates are likely to contain various foreign substances, and old mortar is adhered to the surface of aggregates, resulting in a large quality deviation (Kim et al. 2019).

As such, Recycled Aggregate (RA) is advocated. However, recycled aggregate has been confined only to lower-grade concrete applications, such as pavements, roadwork and sub-base. The major reason is the variable behavior of RA resulted from different concrete waste sources collected for centralized crushing in a centralised recycling plant.

Influence of amount of recycled coarse aggregates and production
In this study recycled coarse aggregates obtained by crushed concrete were used for concrete production. Four different recycled aggregate concretes were produced; made with 0%, 25%, 50% and 100% of recycled coarse aggregates, respectively. The mix proportions of the four concretes were designed in order to achieve the same compressive strengths.
