“…Tran et al [20] developed an aerogel from rice straw and polyvinyl alcohol (PVA) with low densities, high porosities, low thermal conductivities, and good mechanical properties. Ramírez et al [21] recorded a drop in thermal conductivity of mortars incorporated with both rock wool and glass fiber when compared the control mortar. Likewise, Hareedy, Nasr, and Sadek [22] also observed a drop in thermal conductivity in cement bounded boards when rice straw was used to replace fines partially.…”

“…As shown in Table 10, mortars made with natural aggregate have a higher Shore D surface hardness compared to masonry mortars made with recycled concrete aggregate. In addition, it can be seen how the incorporation of aramid fibers does not produce an improvement in this physical property of the material [82]. Additionally, it is observed that the bond strength of the mortar applied on a brick masonry is reduced in the case of mortars made with recycled aggregate, with worse results in the dosages with a cement/aggregate ratio of 1:4 and with the incorporation of fibers being detrimental to this property [83].…”

The reuse of construction and demolition waste is a necessary way to achieve greater sustainability in building, introducing the criteria of the so-called circular economy in the design of the production process of new construction materials. This research focuses on analyzing the properties of mortars made with recycled aggregates from concrete waste and reinforced with aramid fibers. For this purpose, an experimental campaign was carried out, including chemical, physical, mechanical and durability tests, performing a statistical analysis to discuss the different properties analyzed. The results show how the incorporation of aramid fibers in the matrix of cement mortars made with recycled concrete aggregate improves their technical performance and mechanical resistance, thus increasing their application possibilities and achieving similar results in some properties to those obtained with traditional mortars made with natural aggregate.

“…For the preparation of the test samples, indications from UNE EN 13279-2 standard were followed, as well as instructions from studies conducted by Serrano [26] and Piña [27]. Panels measuring 320 ± 1.5 mm x 150 ± 1.5 mm with a thickness of 15 mm were prepared, having a water/plaster mass ratio of 0.8.…”

This article analyzes the effect of fire on plasterboards with aggregates of plastic cable waste, considering the plaster coating as a strategy to reduce the flammability of the added polymers. A real test was performed, using a direct fire set in a Madrid fire station, and a theoretical estimate of the composition of the gas emissions, focused in CO 2 and CO, during a fire in a type room is presented. The results reflect that there is no clear trend between the evolution of temperatures over time and the amount of plastic waste added to the plaster matrix in the different specimens, but a different behavior is obtained depending on the surroundings where they are located. Temperatures of 600 • C are reached between 5 and 10 min after the start of the fire if they are located in a place with heat containment, and they do not reach 400 • C in the same period of time in a place with less heat containment. It was also observed that gypsum can be considered a passive protection of polymers, as it retards the effect of the flame on them. Concerning the gases released, the theoretical calculations, based on the elemental and thermogravimetric analysis of the plastic cable waste, reveal that the amount of carbon dioxide generated in a fire would not pose a risk to people's health whereas the values obtained for the carbon monoxide exceed the limited considered dangerous to health for a period greater than 15 min. Using plastic cable waste as secondary raw material reduces the number of incinerations to be carried out in landfills with this type of waste, thereby decreasing the potential emission of contaminants into the atmosphere and contributing to the sustainability of our planet.
