dc.description.abstractThis paper shows the characterization of a new lightened gypsum-based material for use in buildings. Super absorbent polymer (SAP) Potassium Polyacrylate has been used as main lightener leading to a 20% density reduction. In addition, tests have been carried out with the lightened plaster material reinforced with vermiculite (VER), recycled glass wool (RGW), expanded clay (EC). A significant improvement in physical properties was achieved. After material evaluation, a new precast design was elaborated and tested for its use in building. Physical-mechanical properties of these new material have been studied. A complementary ignitability test was also conducted to set this materials suitability for its use in building. All samples performed over standard minimum requirements. Samples containing RGW obtained best results in both, thermal conductivity, and acoustic absorption. © 2023 Elsevier Ltdes
