Abstract(s)
The conscientious utilization of natural resources and the efficient waste management have
become a matter of great concern in recent years due to the harmful impacts on the environment.
The construction sector presents itself as one of the sectors that most contributes to raw materials
consumption and waste generation, demanding the investigation of more sustainable and ecofriendly
building materials, where the valorisation of wastes originated from other industries
can be promising. Following the sustainability concept in construction materials, this work investigates
the potential use of textile waste in cement-based lightweight construction material,
evaluating the fire reaction of the material using the cone calorimeter equipment. The samples
were tested at three different radiant heat fluxes (35 kW/m2, 50 kW/m2, 75 kW/m2) to simulate
different fire situations. For the highest heat flux, the lightweight construction element with
textile waste incorporation showed a Heat Release Rate Average ≤ 18 kW/m2, a peak Heat
Release Rate Average ≤ 60 kW/m2, and a Total Heat Release Average ≤ 33 MJ/m2. These results
reveal a very satisfactory fire behaviour compared to other materials and show the suitability of
using textile waste as lightweight cement-based materials.
