Abstract

It is known that continuous fiber reinforced sand has anisotropy in deformation and strength characteristics which comes from its construction method. In this study, anisotropy of continuous fiber reinforced sand was investigated through box shear tests and simple shear tests with changing the angle of deposition.
Small amount of cement was added to continuous fiber reinforced sand to increase shear resistance and resistance to erosion. Box shear tests were also carried out.
The reinforcement works most effectively when direction of deposition coincides with the minor principal strain direction. Cement mixing increased shear strength, reduced deformation, and improved resistance to erosion.
