“…The use of gypsum or plaster mortars to produce prefabricated elements is well known since the incorporation of aggregates improves the mechanical rigidity of the material and increases its resistance [26]. In this sense, Santa Cruz-Astorqui et al analysed the behaviour of some original 40 × 20 × 10 cm blocks composed of a sandwich panel with two plasterboards and a core of plaster and EPS, showing that this type of prefabricated material has good deformation capacity under external stresses [27].…”

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.

“…Also, the use of PET waste as partial substitute for sand in concrete was examined by Almeshal et al (2020), achieving a reduction in unit weight in spite of the mechanical strength and fire resistance of concrete decreasing. On the other hand, the incorpoation of PUR waste to gypsum mortar mixes was studied by Vicario et al (2020), leading to porous and lighter mortars, with enhanced resistance to water-vapour permeability, but lower mechanical strength and higher levels of absorbency.…”

“…These brittle qualities will very certainly seriously harm the cast structure when exposed to applied stresses. To improve mechanical properties like compressive and bending strength, fibres like steel fibre, polyester fibre, glass fibre, carbon fibre, polyamide, and polypropylene fibre can be added to gypsum composites [7], [16]- [19]. Gypsum's fibre increases mechanical characteristics, particularly post-cracking behaviour by reducing brittleness [20].…”

Gypsum is a common interior construction material, especially when used as a finishing element. However, interest in prospective uses of gypsum as a finishing component has diminished in recent years as a result of its weak mechanical strength and brittle character, which is essential in interior construction. Therefore, to overcome this challenge, the effect of pineapple leaf fiber on gypsum was investigated. Five different composite configurations of 2%, 3%, 5%, 10%, and 20% pineapple leaf fibre (PALF) with two PALF sizes of 5 mm and 15 mm were prepared and tested after 7 and 28 days of curing. The results of the tests show that materials reinforced with 2% PALF have significantly improved mechanical properties. The compressive strength of a gypsum composite increased by 12.4% when 2% PALF was added. Flexural strength increased by 59% when 2% PALF was added to the mixture. The study provided a means of making gypsum composites having greater mechanical strength than those made from fossil oil-based polymers. It also found relevant use of pineapple leaf, an agricultural waste.
