Abstract

The gypsum soil forms large areas of Iraq soil. Therefore, studying the behavior of this soil and its treatment method is important as the current solution is to replace gypsum soil when starting any construction work. In this study, the gypsum soil was taken from Tikrit city, which has a gypsum content of about 38%, was used. This study aim to present the effect of the polymer on the gypsum soil properties. Meanwhile, the amount of positive effect this material (polymers) will have on the behavior of gypsum soil. The percentages of the additive from polymer (5, 7.5, 10, 12.5, and 15%) were percentages of the weight, and the tests conducted on the soil are chemical tests and physical tests and engineering tests. The results showed that the engineering properties of the soil improved the collapse of soil, was less than (5.11) to (1.21), the cohesion increase (28.98 KN/m3) to (51.16 KN/m3) and the angle of internal friction decrease from (33.190) to (38.850) when the percentage of additive was increased from 0% to 15%.
