The tests were conducted using unconfined
compressive strength (UCS) test after the specimen of fiberesoilecement admixture were cured for some
period. The results show that fiber additive can significantly improve the strength and ductility of the
cement treated Shanghai clay. The UCS of fiberesoilecement admixture is related to both content and
length of fiber. Both two kinds of fiber-reinforced cement clay reached their peak strength at fiber
content of 0.5%. UCS will slowly reverse if the fiber content continues to increase. Even though the
polypropylene fiber works better than the fiber bundles, the difference is less than 5%. These results
indicate that the fiber bundles split from polymer bags can be used as the reinforcement in soil mixing,
thus providing a novel approach to treat waste polymer textile bags
