Abstract

In order to investigate the strengthening mechanism of modified polypropylene fiber reinforcement cement stabilized soil (MPFRCSS), the unconfined compressive strength (UCS) was used to test the performance of soil with different fiber contents, different cement contents, and different maintaining conditions. The results indicated that the chemical effect (hydration reaction) of cement and physical effect (anti-crack effect) of fiber worked together, and the double reinforcement greatly improved the mechanical property of soil, especially for early strength, the UCS of soil increased form 1.21MPa to 4.42MPa, the growth nearly 4 times. The appropriate contents of fiber should be 0.3% to 0.45%. Through the observation of failure shapes, the soil showed an obviously brittle failure with the increased of cement content, and the failure mode would greatly changed from brittle failure to plastic failure with the incorporation of fiber.
