Use of Sawdust Fibers for Soil Reinforcement: A Review

A frequent problem in geotechnics is soils with inadequate physical–mechanical properties to withstand construction work, incurring cost overruns caused by their engineering improvement. The need improve the of not recent. most common current alternatives are binders such as cement and lime. climate change observed recent decades uncontrolled emission greenhouse gases have motivated geotechnical geoenvironmental researchers seek mechanisms for soil reinforcement from a more sustainable environmentally friendly approach proposing use recycled waste materials. An alternative natural fibers, which can be obtained many agro-industrial processes, due high availability low cost. Sawdust, by-product wood processing, has rough texture that generate friction between fiber matrix soils, leading significant increase its shearing strength bearing capacity. This concept improving using fibers distributed randomly inspired phenomenon grass and/or plants that, when growing on slope, effectively stabilize said slope.
