Descripción
This work studies the physical and mechanical behavior of a light gypsum eco-mortar, made with aggregates from ceramic waste and extruded polystyrene (XPS) waste. The main objective to include waste into the gypsum compound is to reduce the amount of raw material used (gypsum) and thus reduce the environmental impact, improving the characteristics of a gypsum without additions to be applied as coatings that require hardness values higher than usual and even better behavior against water. For this, gypsum samples of dimensions 4x4x16 cm were made to which different percentages of the residues were added according to the weight of the plaster (1%, 2% and 3% of XPS and 25% and 50% of ceramics) and also reference samples (without additions). These specimens were tested in the laboratory and the following characteristics were determined: dry density, surface hardness, flexural strength, compressive strength, water absorption by capillarity and adhesion. After a comparative analysis, the following conclusions were drawn: it is possible to elaborate gypsum mortars with addition of XPS and ceramic residues and that these gypsums reduce the water absorption by capillarity and increase the surface hardness of the reference gypsum without additions
