- Abstract
In this paper, an experimental program was reported to investigate the effects of polyester fibers on the mechanical properties of cement treated clay soil. Five different fiber contents and same number cement content were randomly inserted into the soil. Thirty samples were prepared and stored in the curing box for seven, twenty-eight, and ninety days, respectively, and then subjected to unconfined compressive tests and indirect tensile tests. It was found that the values of tests increased as the fiber content and curing time increased. Fiber inclusion improved the ductile failure characteristic of soil. From results of the test, there was a certain linear relationship between two kinds of strengths. The micro structures were obtained from scanning electron microscopy (SEM) analysis. It was found that a strong cohesive force obstructed the relative sliding between fiber and cement-soil mixture.
