“…On the other hand, the incorporation of mineral wool residue improves the flexural strength of the hardened plaster mortar. This is in line with other studies that highlight the beneficial effect of the incorporation of fibres in the mortar matrix to improve its ductility and deformation capacity [56,57]. Regarding recycled aggregates, mortars that incorporate sand from concrete waste have better performance than mortars with aggregates from mixed ceramic waste.…”

The high demand for natural resources and increased industrial activity is driving the construction sector to search for new, more environmentally friendly materials. This research aims to analyse plaster mortars with the incorporation of construction and demolition waste (CDW) to move towards a more sustainable building sector. Three types of aggregates (natural, recycled concrete and recycled from ceramic walls) and two types of insulation waste (expanded polystyrene with graphite and mineral wool) have been added to the plaster matrix to evaluate its mechanical and physical properties and its suitability in the elaboration of prefabricated materials. The results show how plaster mortars made with recycled aggregates have higher mechanical resistance than conventional plaster without incorporating sand. The incorporation of crushed mineral wool residues improves the flexural strength of plaster mortars and their application in the execution of prefabricated panels. Likewise, the expanded polystyrene residues reduce the final density of mortars, improving their behaviour against water absorption and reducing the final thermal conductivity of plaster material.

“…With the addition of mineral wool fibers, the greater the content of mineral wool fibers, the less the flexural strength. Although works show that mineral wool fibers can increase mechanical strength [50][51][52][53][54][55][56][57][58][59] when replacing cement, sand or aggregate, they were added and mixed with cement and sand.…”

“…Thus, they lose, the definition of sustainable, ecological constructions but gain durability. However, we can find another architecture that seeks to improve the properties of the traditional construction systems with the incorporation of renewable materials [27]. In recent years, authors have proposed the incorporation of mass rat the earthen mixtures due to the great resistance they provide, the reduct nance and the adaption to current standards [25].…”

This research focuses on the addition of an ecological, sustainable material to improve the durability of earthen constructions and for use in rehabilitation and restoration processes. Specifically, it studies the mechanical and waterproof performance of an earthen mixture with the addition of a vegetal origin gel (VOG) obtained by extracting the starch contained in rice. This solution increases the durability of the mixture and the behavior against water and improves the mechanical resistance of the system. This study is divided into two parts. First, an experimental phase was carried out in the Universitat Politècnica de Catalunya laboratory to design and develop the earthen mixtures stabilized with VOG to obtain an ecological, economical and easily replicable technology that can be transferred to any population group. The second stage consisted of the application of these mixtures and a real intervention in adobe dwellings in the community of Santa Ana Chapitiro, in the State of Michoacan, Mexico. The rehabilitation solutions and dosages were transferred to the residents of the community and applied to local adobe constructions by means of participatory design through an international development cooperation project. Good behavior of the material was found in the early stage.
