We investigated the effect of adding nano-wollastonite on the physical, mechanical and morphological properties of gypsum Composites. The ratio percentage of bagasse mixing as lignocellulosic material with gypsum at three levels (85:15; 75:25; 65:35) and nano-wollastonite at three levels of 0 %, 5 % and 10 %. Specimens were prepared according to the ISO 11925 specifications for the fire resistance (weight loss) properties and according to the DIN EN 634-1: 1195-04 specifications for the mechanical and physical properties. Scanning Electron Microscopy (SEM) were also used to study the properties of composite morphology and distribution of samples. The results showed that by increasing the amount of nano wollastonite, physical and mechanical properties improved. The MOR, MOE and IB of boards decreased with increased bagasse usage amount, and its maximum value was obtained in using 15 % bagasse. The results also showed that increasing the amount of bagasse in boards caused a significant increase in the TS of the boards. The results from microscopic images showed that the optimal level of nano-wollastonite can fill the empty holes and create a uniform structure, thereby improving the properties of the boards.
