Pullout Response of Ferrocement Members Embedded in Soil

The synergetic actions from two components of mortar and wire mesh may allow ferrocement, a reinforced cementitious composite, to attain its optimal soil reinforcement applications' reinforcing capability. Some experimental results on the failure modes and performance behavior of ferrocement elements reinforced with chicken mesh and woven square mesh under pullout tests under two backfill material types are presented. That ferrocement failure modes depend on ferrocement surface properties, type of mesh, and mortar composition is demonstrated. Test results reveal that with chicken mesh-reinforced ferrocement, mortar fails at higher normal stresses, while with square mesh-reinforced ferrocement with smooth surface only under stresses is frictional failure shown. That ferrocement's pullout resistance is significantly improved through the use of some small parallel channels on the ferrocement element surface transversely to the pullout direction. Only mortar failure, in the case of two, four, and six-channel containing ferrocement, is observed for square mesh-reinforced ferrocement, while for chicken mesh-reinforced ferrocement, there is apparent mesh failure. A discussion regarding ferrocement element corrosion as embedded in soil and a comparison of other soil reinforcement methods, such as geosynthetics or geogrids, with this one in terms of durability, strength, and cost, is presented.
