Thermal Analysis of Recycled Gypsum from Construction and Demolition Waste

Abstract:

Construction and demolition waste has in its composition gypsum plaster which is a soil and groundwater contaminating material. Some works have been developed to recyle this gypsum waste. The aim of this work is to show a thermal analysis of recycled plaster. The recycled plaster was produced through a recycling process consisting of grinding and burnig the gypsum waste. Physical and thermal properties (TGA/DTA) from both commercial and recycled gypsum plaster were analysed. The results show a recycled plaster with similarities with commercial plaster, showing the possibility to reuse this waste in construction works.
