Performances of Sandy Soil Stabilization with Fiber and Cement

Abstract

To study the influence of polypropylene fiber on the strength of sandy soil stabilization with cement in flooded area of Yellow River, a series of experiments 7-day unconfined compressive strength have been done when samples reach 7-day standard curing. Based on the data, it is found that fiber content has an important influence than its length on unconfined compressive strength. As for failure modes, there are significant differences between the samples of adding fibers and those adding nothing. After adding 10 % cement, 1 fiber with 12 mm single length, the unconfined compressive strength of sandy soil stabilization with cement can be greatly improved with increase rate of 83%. It is concluded that the sandy soil can be successfully stabilized by the combined action of fibers and cement.
