Utilización de material compuesto de escayola para la elaboración de productos prefabricados sostenibles: estudio de su proceso de fabricación, propiedades y cadena de suministro

Use of composite plaster material for the development of sustainable prefabricated: study of its manufacturing process, properties and supply chain

Abstract

The building sector is currently involved in a process of

change as a result of concerns about the sustainability of

the construction industry. For this reason, the application

of circular economy criteria that are committed to the

development of new, more sustainable construction materials

has become one of the major challenges included in the

European Green Pact. In this research, the physical and

mechanical characterisation of a new plaster composite

material with the incorporation of recycled rubber granular

particles and glass wool waste fibres has been carried out. It

has been possible to replace up to 30% of the original plaster

material with recycled raw material, improving the thermal

behaviour of the prefabricated plaster plates. In addition, good

mechanical performance has been obtained and the weight

of the precast elements has been reduced. Finally, using the

FlexSim simulation software, different scenarios have been

examined which have permitted to know the increases in

productivity in the manufacturing process derived from the use

of these lightened sustainable materials, as well as to verify the

reduction in fuel consumption (litres/plate) and CO2 emissions

during transport. For all these reasons, the implementation

of circular economy criteria applied to waste management

is fundamental to progress towards the achievement of the

Sustainable Development Goals.
