The purpose of this study is to determine the impact of adding Tree Glue Powder (TGP) and Silica Fume (SF) powders (by weight) alone and in combination on the characteristics of gypsum plaster. The study will focus on two critical gypsum properties: compressive strength and setting time. According to the study plan, a total of twelve specimens will be utilized. The twelve specimens were divided into four groups according to their TGP and SF contents (by weight), which were (0.0 percent), (1.0 percent) for (TGP) and (0.0 percent), (1.2 percent) for (SF) respectively. Three cubic (5 × 5 × 5 cm.) specimens were used to determine the average outcome for each blend. The ratio of water to gypsum plaster (W/P) was set at (0.5) for various mixtures. It was discovered that by adding just (SF) to Gypsum plaster mixtures, compressive strength is increased while setting time is decreased. On the other hand, adding merely (TGP) to the mixtures reduces compressive strength while significantly increasing setting time. Additionally, it was discovered that when both additives (SF) and (TGP) were used, two benefits were acquired, namely an increase in compressive strength and a minor increase in setting time(as compared to the no additives reference case).
