Abstract
The study investigated the improvements in strength and crack resistance induced by the introduction of wool fibres in an earthen material. Earthen samples reinforced by wool fibres of various fibre lengths at different fibre weight fractions were tested under flexural loading to examine the structural response of the material in terms of first-crack resistance, post-cracking residual strength and energy absorption capability. It was found that the fibrous reinforcement greatly improved the residual strength, the ductility and the energy absorption of the reinforced material as compared to the unreinforced soil. The results of the study also showed that fibre length had a notable influence on the post-fracture response of the material at large deformation regimes.File | Size | Format | |
