Abstract: The construction sector is responsible for a third of the total wastes produced by the European
Union members. Ceramics produce some of the wastes in this sector. Sanitary ware is one
example of a white ceramic waste, both in the industrial process and in buildings’ demolition.
The introduction of sanitary ware in hydraulic elements as a substitute of natural aggregates has
been studied by some authors. In mortars, the presence of sanitary ware presented improved
mechanical behaviour by comparison with a similar mortar with natural aggregate, namely an
increase of the flexural and compressive strengths. Nevertheless, it was also noticed that this
waste increased the mortars’ micro-cracking.
In this research, textile fibres were incorporated in mortars with sanitary ware waste content to
prevent micro-cracking of these elements. Five mortars were analysed: a reference mortar, a
mortar with 20% of sanitary ware as filler, another with 100% of sanitary ware (total replacement
of sand) and two others with the same sanitary ware contents but with 5% of textile fibres.
The deformability and mechanical performance of all mortars were analysed over time. It was
found that the textile fibres addition increased the fracture energy and decreased the modulus
of elasticity of sanitary ware mortars, which resulted in an improvement of deformability and
mechanical performance.
