EFFECT OF POLYPROPYLENE FIBERS ON THE STRENGTH AND ELASTIC MODULUS OF SOIL-CEMENT

摘要

The effect of the content and types of polypropylene fibers which are mixed into the soil-cement mixtures on the strength and elastic modulus of soil-cement isare studied. The test result shows that the unconfined compressive strength of soil-cement, if within a certain range increased with the increasecontent of polypropylene fiber content. Otherwise, the strength falls off consequently when the fibers proportion increased over this range. The elastic modulus of soil-cement decreased along with the increase of fibers. Moreover, both the strength and elastic modulus of soil-cement increased with the content of cement.
