Lightweight recycled gypsum with residues of expanded polystyrene and cellulose fiber to improve thermal properties of gypsum

In this study, different proportions of gypsum composite reinforced with recycled cellulose fibers and expanded polystyrene were produced to study the properties thermal conductivity, density, flexural strength be used as sealing plates improve comfort buildings. Different matrix composites varied fiber polystyrene, analyze influence residues on material. The conductivity obtained for greater amounts was 0.18 W/mK, a 48% reduction in relation plasterboard, improving performance. also analyzed, which met minimum requirement use composites, however, it is not enough places that require mechanical resistance, thus indicated applications, performance where only plasterboard used.
