For composite production, gypsum mass was substituted with different proportions of Miriti: 2.5%, 5%, 7.5%, and 10%. The manual mixing of gypsum, water, and Miriti was conducted within a 2.5-minute timeframe, followed by molding into forms with dimensions of 200x200x15 mm. The board faces were coated with cellulose pulp, a common practice in the application of gypsum plasterboard in drywall systems. After a 24-hour period, the boards were removed from the molds and placed in a climate chamber with a temperature of 20 ± 2 °C and relative humidity of 65 ± 3% for 28 days. Subsequently, test specimens were extracted for the execution of physical-mechanical and thermal tests. The Miriti-containing gypsum plasterboards exhibited lower bulk density, resulting in lightweight materials. Both Miriti-reinforced and unreinforced gypsum plasterboards met the requirements specified in EN 13279-1 (2008) for flexural strength (MOR), which establishes a minimum value of 1 MPa for gypsum-based construction materials. Composites with 2.5% and 5% Miriti also fulfilled the demands of EN 13279-1 (2008) for compressive strength, which sets a minimum value of 2 MPa. Composites with 7.5% and 10% Miriti showcased the highest thermal resistance values. The use of Miriti co-products demonstrated promise for various applications in the construction industry, enabling value addition and appropriate final disposition of this lignocellulosic material.
