Abstract

Gypsum boards had poor dimensional stability and mechanical properties compared to cement boards. To improve its properties, gypsum–cement boards reinforced with kenaf fibre bast using different gypsum/cement mixing ratios was fabricated in the current study. The results revealed that addition of cement generally improved the bending strength and compressive strength of the gypsum boards. Dimensional stability attributes, water absorption and thickness swelling, were also enhanced along with increasing cement ratio. Significant improvement was observed when 70% cement was added whereas the effects of adding 30–50% on properties improvement are not significant.
