A Study on Shear Strength for Dune Sand Reinforced With Shredded Waste Tyres
Journal Title: American journal of Engineering Research - Year 2017, Vol 6, Issue 10
Abstract
This paper presents the general study on shear strength for dune sand reinforced with shredded waste tyre. The reuse of tyres shreds may not only address growing environmental and economic concerns, but also help solve geotechnical problems associated with low soil shear strength. Laboratory tests were conducted in large scale direct shear test apparatus to investigate the feasibility of using shredded waste tyres to reinforce dune sand. In tests were conducted on a matrix of dry dune sand mixed with waste of shredded tyres. Tyre shreds were randomly mixed with dune sand. Tyre shred contents were varied from 2%, 6% and 8%.The effect of factors such as shred length was also studied. A number of identical samples were tested under increasing normal loads and the required maximum shear force was recorded. The results of these tests are plotted with normal stress along horizontal axis and shear stress that produced failure of the specimen along vertical axis. A straight line, called strength envelope is drawn connecting the points and is extended to intersect vertical axis.
