AbstractThe objective of the present work is to improve physical and mechanical properties of local gypsum reinforced with Resole resin. The water-gypsum ratio was kept at 45% throughout all these experiments. The prepared composites show a clear improvement in impact, compression strength and modulus of elasticity while, the bending strength is reduced when the Resole resin proportion in gypsum was increased from 2.5 to 10%. The other objective of this study was to evaluate the water absorption of Resole –gypsum composite. From the experimental results it may be concluded that swelling % was reduced when the Resole percentage in gypsum- Resole composite was increased.
