AB [EN] The use of construction and demolition wastes (C&DW) is a trending future option forthe sustainability of construction. In this context, a number of works deal with the use of recycledconcrete aggregates to produce concrete for structural and non-structural purposes. Nowadays, animportant number of C&DW management plants in the European Union (EU) and other countrieshave developed robust protocols to obtain high-quality coarse recycled aggregates that comply withdifferent European standards in order to be used to produce new concrete. The development ofself-compacting concrete (SCC) is another way to boost the sustainability of construction, due to theimportant reduction of energy employed. Using recycled aggregates is a relatively recent scientificarea, however, studies on this material in the manufacture of self-compacting concrete have proventhe feasibility thereof for conventional structural elements as well as high-performance and complexstructural elements, densely reinforced structures, difficult-to-access formwork and difficult-to-vibrateelements. This paper presents an original study on the use of coarse recycled concrete aggregate(CRA) to obtain self-compacting concrete. Concrete with substitution ratios of 20%, 50% and 100%are compared with a control concrete. The purpose of this comparison is to check the influence ofCRA on fresh SCC as well as its physical and mechanical properties. The parameters studied arematerial characterization, self-compactability, compressive strength, and tensile and flexural strengthof the resulting concrete. The results conclude that it is feasible to use CRA for SCC production withminimal losses in the characteristics.
