“…For the elaboration of this study, four different types of fibers have been used, which can be classified according to whether their origin is synthetic or natural. The synthetic fibers used are: alkali-resistant glass fiber whose main components are: SiO 2 (62%), ZrO 2 (17.3%) and Na 2 O (14.30%), basalt fiber chemically composed of: SiO 2 (47%), Al 2 O 3 (13%), CaO (12%), MgO (10%) and polypropylene fiber [44][45][46], supplied by the company SIKA, Madrid, Spain. The natural fiber used is wood fiber from Scots pine consisting of sawdust fibers supplied by Salesianos Carabanchel High School, Madrid, Spain.…”

This paper shows the characterization of a new lightened gypsum-based material for use in buildings. A plaster material has been designed with a polymeric compound based on polyvinyl acetate, bicarbonate and a boric acid solution, which reduce the density and thermal conductivity by up to 20% and 30%, respectively. In addition, tests have been carried out with the lightened plaster material reinforced with glass (GF), basalt (BF), polypropylene (PPF) and wood (WF) fibers. A significant improvement in mechanical properties was achieved. All samples obtained resistance values greater than 2 MPa in flexion and 3 MPa in compression. Physico-chemical analysis were also carried out. The study is completed with a statistical analysis, where confidence intervals have been obtained for the mean at 95% confidence for each of the physical properties studied.

“…Based on this regulation, the hydraulic conglomerate used in this research is of the CEM II/B-L-32.5 N type. It is a cement made up of clinker, limestone and up to 5% of additions [42], very commonly used on site for economic reasons and for its good technical performance [43]. Table 1 shows the chemical composition of this material obtained by X-ray fluorescence technique.…”

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.

“…These mortars with recycled aggregate are characterized by a lower density, which leads to a lower compressive strength compared to traditional mortars [24]. In addition, this lower density is related to a lower compactness of the mortar matrix, so they have higher capillary water absorption coefficients [25]. On the other hand, the higher fines content of recycled aggregates has an impact on the greater demand for mixing water in this type of mortar to obtain a plastic consistency [26].…”

The environmental problems caused by industrial waste are of a universal nature. In this sense, achieving an adequate management of construction and demolition waste has become one of the great challenges of today’s society. This work studies the possibility of recovering mineral wool thermal insulation waste for its reincorporation into the manufacturing process of masonry mortar. To this end, an experimental campaign has been conducted with mortars made with natural aggregate and two types of recycled aggregates: concrete and mixed ceramic, in which mineral wool fibers are incorporated as a partial replacement of sand in percentages of 0%, 10% and 20%. The results show that, although the traditional mortars offer better technical performance, the mortars made with recycled aggregate present adequate viability for use on-site. Furthermore, it has been concluded that the incorporation of recycled mineral wool fibers in the mortar matrix decreases the thermal conductivity and shrinkage during the setting of these materials, increasing their mechanical flexural strength and durability.
