“…Many research works dealing with cement mortars have been conducted which incorporated different types of waste, such as ceramics and concrete [6][7][8], insulation materials [9][10][11], wood waste from demolition [12], or ladle furnace slag [13]. Most of these studies deal with recycled aggregates of concrete and ceramic waste.…”

This article analyzes the feasibility of using construction and demolition waste (expanded polystyrene, ceramic, and concrete waste) in a gypsum matrix to manufacture plaster for interior coatings or for prefabricated elements for interior partitions. To do this, several gypsum specimens were prepared (4 × 4 × 16 cm) incorporating different percentages of waste based on the weight of the gypsum (25%, 50%, and 75% of ceramic, concrete, and a mixture of both). Reference samples were also produced (without additions) to compare the results obtained. The compounds with the best performance were selected and lightened by preparing other samples in which 1/3 and 2/3 of the volume of ceramic, concrete, and mixed waste were replaced with expanded polystyrene (EPS). All samples were tested in the laboratory and the following physical and mechanical characteristics were determined: density, surface hardness, flexural strength, compressive strength, capillary water absorption, and thermal conductivity. Several applications were proposed for the selected compounds. A gypsum block with a sandwich configuration was obtained (40 × 20 × 10 cm) using the optimum compound. The block was further tested regarding its density and compression strength. A comparative analysis showed that it is possible to produce materials with a gypsum matrix by adding ceramic, concrete, and EPS waste, improving the behavior of the traditional gypsum and enabling them to be applied in various construction applications. These applications have a lower environmental impact than ordinary ones because they use less primary raw material, due to the reuse of waste.

The objective of this study was to analyze the physico-mechanical properties of gypsum boards including plastic waste aggregates from cable recycling. The plastic cable waste is incorporated into the gypsum matrix without going through any type of selection and/or treatment, as it is obtained after the cable recycling process. In the experimental process, gypsum boards of different dimensions were manufactured and tested for their Young’s modulus, shock-impact resistance, flexural strength, thermal conductivity, and thermal comfort. The results obtained show a significant increase in the elasticity of the boards with plastic waste (limited cracking), compliance with the minimum value of flexural strength, and a slight improvement in the thermal conductivity coefficient (lower energy demand) and surface comfort (reduced condensation and greater adherence). Therefore, the analyzed material could provide a suitable alternative to currently marketed gypsum boards, contributing to sustainable construction not only in new constructions, but also in building renovations.

“…The experimental plan was designed in three phases, with Phase 1 and Phase 3 being carried out in the materials laboratory of the Higher Technical School of Building of the Polytechnic University of Madrid, and Phase 2 in the facilities of the Fire Prevention and Extinction Service of the Community of Madrid. Shore D hardness, flexural and compression strength tests were performed following the methods described in a previous work [7], and the thermal conductivity of the mortars manufactured with the three types of fibre residues was calculated before exposing them to fire.…”

“…More specifically, the aim is to recycle mineral wool residues from insulating materials found in construction and demolition waste, since the growing importance of thermal insulation in the construction sector [6] has led to an increase in the use of mineral wool and therefore its waste. This ensures that non-recyclable mineral wool waste is not unusable and is a valuable resource through its recovery and an alternative to the reinforcing fibres currently used [7].…”
