RESULTS OF TESTS TO DETERMINE THE FEASIBILITY OF STABILIZING SOILS CONTAINING GYPSUM WITH LIME AND CEMENT

摘要

The purpose of the tests reported herein was to evaluate the effectiveness of lime and cement to stabilize a soil containing an appreci¬able percentage of calcium sulphate (CaSO4 - 2H2O), commonly referred to as gypsum. Soil used for the tests was obtained from Perrin Air Force Base, Texas;this soil contains gypsum in its natural state. Con-ventional laboratory soil tests were used for the determination of the physical properties of the natural soil and to determine what, if any, strength gain or property change resulted when varying percentages of hydrated lime or cement were added to the soil and the mixture allowed to cure for different periods of time.
