Abstract: | Plaster composites have been developed by the authors, aiming the manufacture of plasterboards and other building materials
with enhanced properties. Polymeric plaster composites,obtained from hydration of commercial plaster of Paris with aqueous
solutions of a commercial polyester, were characterized by thermogravimetry (TG) and differential thermal analysis (DTA).
A method using derivative thermogravimetry (DTG) was developed to determine the polymer content in the composites and its
distribution. Samples prepared conventionally by hydration of plaster of Paris with water were used as reference. Independently
of the initial solution concentration, all the composites show an even distribution of the polymer, which presence enhances
the composite mechanical strength.
