EFFECT OF CREEFFECT OF CREEP RATE ON BEHAVIOR OF CLAY - CEMENT SOIL.EP RATE ON BEHAVIOR OF CLAY - CEMENT SOIL
Journal Title: International Journal of Advanced Research (IJAR) - Year 2018, Vol 6, Issue 3
Abstract
This research is to investigate the time- dependent behavior of a clayey soil-cement. The traixial compression test was utilized throughout the test programs under the unconsolidated undrained condition. The undrained condition represents the controlling drainage condition in which a creep failure may occur. The undrained creep behavior of soil-cement was investigated. In addition to the cement content, three various stress-strength levels were examined. The creep time relation, effect of stress level on creep, effect of cement content on creep, creep rate, and the effect of creep on strength was studied thoroughly. Test results showed that creep strain increases with logarithm of time and stress level increase but decreases as the cement content increase. Also, increase in strength and modulus of elasticity augment after creep but, was affected by increase in cement content. In the other side, this research shows a particular stress level below which soil-cement sample will not fail; this is termed the critical stress level. Little increase in critical stress level was found with increase in cement content. Finally linear relationship appears between logarithmic of creep rate and time, the slope of this relationship was found to be independent of stress level. Creep strain decrease rapidly with logarithmic of creep rate for specimen of 0% and 4% cement content while insignificant changes in creep properties occurred in specimens with 8% and 12% cement content.
