Wall reinforcement load-bearing capacity

The tests of the specimens under compressive load proved a considerable increase of bearing capacity due to fibres. The descending branch of the load-deformation curve is long and its shape is strongly related to the kind of fibres used. In the case of elastic fibres a quasi-linear behaviour is observed, but for ordinary polymeric fibres the elastic quasi-plastic behaviour should be expected. Thanks to the artificial cohesion, the reinforced sand is used for construction of walls and slopes with steep gradients between 60° and 90° also in various geotechnical works (Aldea 2007).
