Soil improvement can be achieved through mechanical stabilisation using industrial byproducts. Clayey soils were blended with waste foundry sand to examine its influence on the geotechnical engineering properties of the soils. The waste foundry sand was first subjected to standard geotechnical engineering testing. The effect of the foundry waste sand on the modification of the plasticity, swell potential, compaction characteristics and CBR values of the soils is demonstrated in this paper. The results show that the addition of waste foundry sand improves the performance potential of otherwise marginal materials for use in geotechnical engineering applications.
