Abstract
Karstic rocks exist in different areas of the world having by case useful/harmful structural and environmental impacts. These rocks like gypsum and salt are dissolved against water.
In the current research, gypsum solubility is investigated by collecting outcomes of several experiments on crushed gypsums. During the tests, rates of gypsum solubility were measured and appraised through application of various parameters such as compaction quantity, period of water flow inside specimen as well as diameter of the initial trial hole increase.
The initial trial holes’ diameters were 0 (in the specimen without hole), 5, 8, 10 and 12 millimeters. Two compaction cases were comprised; with and without compaction. Furthermore it should be mentioned that flow of water was continued inside the specimens for a period of 3, 10, 20 and 30 days in the separate experiments in order to assess the time factor on the solubility quantity of the gypsum. Solution rate respectively for crushed gypsum were computed 2.49 cm/year. These experiments indicate that progress of solution phenomena does not have a particular trend.
