Pumice
and textile fibers, by-products of the textile industry—especially from denim
washing—pose environmental waste challenges. This study explores using pumice
as aggregate replacement in cement mortars and adding textile fibers in dry
form, as well as two wet methods: pre-soaking fibers before mixing and adding
fibers to mixing water. Cementitious mixtures with 3% fibers were compared to
fiber-free references. Their
effect was evaluated based on workability, compressive, and flexural strength
tests. Results indicate the feasibility of lightweight pumice with a porous
structure as aggregate. The optimum balance between workability and strength
was found at 3% fiber content. Wet-added
fibers showed better workability; however, adding fibers to the mixing water
method provided the most homogeneous distribution and was thus selected. These
mortars have demonstrated applicability in non-structural uses such as urban
furniture. These findings highlight the potential of textile industry
by-products as sustainable construction materials.
