Behavior of Lime Stabilized Gypseous Soil under Different Condition

Abstract

This research work aims to study the variations taking place (occurring) in the strength and strain of lime stabilized gypseous soil specimens with different degree of saturation when subjected to different conditions. Those conditions include stages where by (Specimens soaked in water of 25°C temperature, no soaking but specimens are at ambient temperature of 25°C, soaking in water of 60°C temperature and no soaking but specimens are at ambient temperature of 60°C). At the above-mentioned conditions the specimens were loaded with a pre-determined calculated of unconfined compressive strength, these loads were increased in a cumulative manner up to failure.The results showed that the soil strength reduced by (21, 12 and 8%) under the 1st three envisaged conditions respectively when compare with the control original specimen. Also the temperature of the soaking water has marked effect on strength indicating an increase of (18%) in the samples in water of 60°C. Contrary to the strength results the strains increased by (2.24, 1.67 and 1.44) for the same above mentioned conditions as compared to the control specimen at a primary saturation condition (94%).
