Abstract

Soft soil from construction sites and disaster areas with low strength is considered as solid waste. Therefore, it is necessary to recycle soft soil for reusing in construction. This research focuses on studying the behaviors of modified soil produced by using fiber and cement. The current study carries out experiments to investigate the influence of fiber on cemented soil. The laboratory experiments including splitting tension test and unconfined compression test are conducted. Corn husk fibers produced from crop residue of agriculture are used to reinforce cemented soil. The corn husk fiber content is 0%, 0.25%, 0.5%, and 1%. The used cement content is 1% and 2%. The results show that fiber inclusion improves both failure strength from unconfined compression test and failure tensile strength from splitting tension test. The highest increase of failure strength and failure tensile strength of cemented specimens is 35.3% and 72.6% when fiber content is 1%, respectively. Fiber inclusion changes the behavior of specimens from brittle to ductile. Moreover, corn husk fiber makes a contribution to the reduction of loss of post-peak stress. The increase in fiber content leads to a decrease in loss of post-peak stress.
