“…Salesa et al [ 6 ] reported that the quantity of cement paste from RA has a greater influence on the water requirement of the mix. An increase in old cement paste increases the quantity of unhydrated cement paste volume, which requires a greater water content to achieve the same workability.…”

“…Apart from this, it also reduces the overall footprint of concrete by a reduction in carbon dioxide (CO 2 ) emission [ 6 , 7 ], and energy associated with it. Usage of waste materials leads to a circular economy [ 8 ] which will respond to environmental challenges as shown in Figure 1 .…”

This article presents an overview of the bibliographic picture of the design parameter’s influence on the mix proportion of self-compacting concrete with recycled aggregate. Design parameters like water-cement ratio, water to paste ratio, and percentage of superplasticizers are considered in this review. Standardization and recent research on the usage of recycled aggregates in self-compacting concrete (SCC) exploit its significance in the construction sector. The usage of recycled aggregate not only resolves the negative impacts on the environment but also prevents the usage of natural resources. Furthermore, it is necessary to understand the recycled aggregate property’s role in a mixed design and SCC properties. Design parameters are not only influenced by a mix design but also play a key role in SCC’s fresh properties. Hence, in this overview, properties of SCC ingredients, calculation of design parameters in mix design, the effect of design parameters on fresh concrete properties, and the evolution of fresh concrete properties are studied.

“…In the studies in which the recycled aggregate was applied, it was observed that some characteristics that differ from the natural aggregates such as heterogeneous composition, high porosity, high fines content, irregular grain shape and rough texture [12] [13]. In the case of high fines, these materials are used as a composition of the fine aggregate [9] [14] and analyzed as part of the aggregate, bringing some complications to the production and properties of the concretes or mortars obtained.…”

“…When the fines are not used as composition of the FRA they are discarded [15], which environmentally is not an adequate solution, since the volume of this fraction is usually high. Although the characteristics of the AR are different from the natural aggregates (NA), the use of RA in the construction industry has proved feasible, since it reduces CDW storage areas and minimizes costs with the obtaining and commercialization of new aggregates [13].…”
