Improvement of Gypsum Properties Using S.F.Additive
Dr. Ahmed S. D. AL-Ridha | Ali A. Abbood [2] | Hussein H. Hussein
Abstract: In this research an attempt has been made to study the effect of adding S. F. additive (by weight) to improve gypsum properties (compressive strength, bulk density, and porosity). The research plan consists of using nine mixes of gypsum which had been divided in to three groups according to S. F. content (by weight) 0.0 %, 0.6 %, and 1.2 %. Each group was divided in to three sub-groups according to (water/gypsum) ratios (0.3, 0.35, and 0.4). It was found that, the addition of S. F. to the gypsum mixes, increases the compressive strength and bulk density, but deceases the porosity. It was also found that, the compressive strength and bulk density were decreased with the increase of (water/gypsum) ratios, Whereas, the porosity increases.
