Abstract: Recycled aggregates can be used in many applications both in building and in civil engineering
field. This research presents the study of mortars made with recycled fine aggregates to be used
as material to design indoor furniture.
Firstly, recycled mortars were designed using three different replacement percentages: 0% as
baseline mortar, 25% and 50% of recycled fine aggregates replaced by natural sand. They were
mixed in the batcher adding extra water to compensate the higher water absorption of recycled
sand compared to that of the conventional one. Fresh and hardened properties of these mortars
were obtained and analysed.
In fresh state, air content and workability were obtained. Regarding hardened properties,
compressive strength and flexural strength were determined at different ages, 1, 3, 7, 28 and 90
days, and also, the water permeability and shrinkage performance. Based on these results, the
most suitable mortars have been chosen to be used as material to design a bathroom sink.
Additionally, some specific surface treatments were tested in order to improve the mortar
performance under aggressive agents that there may be usually in a bathroom. Finally, a sink
prototype was designed with these recycled mortars.
