ABSTRACT |
The use of natural and artificial textiles is a suitable method for homogeneous soil reinforcing. This method is considered on the condition of optimum mix and suitable moisture. In this project reinforced kaolinite samples with metal fibers with two different moisture content assessed with axial compressive test. Results shows that metal fibers augmenting with random arrangement cause to increase axial compressive strength of kaolinite clay. Strength augmentation is a function of length, bend angle and amount of fibers weight percentage in mixture. Generally metal fibers amount augmentation cause to increase axial compressive strength of soil This augmentation depend on length to diameter ratio of fiber. In addition to this factor the bend angle type has a considerable effect on kaolinite clay strength level in the way that bent fibers in comparison with straight fibers cause to more strength increase in clay. Also moisture content augmentation cause to decrease axial strength.
Keywords: kaolinite, fiber, axial strength, length, bend angle, weight percent.
