Abstract: Gypsum boards are commonly known as drywall, plasterboards, Sackett board or wallboard. These boards are made of calcium sulfate dihydrate (CaH4O6S). common gypsum boards contain paper as a thickener for less consumption of gypsum powder. The focus of the study was to develop a suitable mixture of cogon pulps in gypsum boards (Imperata cylindrica) as a substituting agent and a thickener for gypsum boards for which the researchers refer as the “cogoflex.” Modulus of rupture, Screw pull resistance, weight per unit area, surface fire test, water absorption and thickness swelling test were performed in the study. The percentage of cogon pulps used to add to the mixture of the specimens are 0%, 5%, 10%, 15%, and 20%. The researchers were able to determine the most suitable proportion of cogon pulps that will be added to the mixture of gypsum.
