Soil Stabilization Using Steel Slag and Sodium Lignosulfonate

This research paper deals about the experimental study on the stabilization of soil using steel slag and sodium lignosulfonate. A series of tests to find compaction properties and unconfined compressive strength have been conducted. The effect of (0, 4, 8, 12, 16) percentages of steel slag combined with (0, 1, 2, 3, 4) percentages of sodium lignosulfonate has been studied. All the sodium lignosulfonate and steel slag samples are cured for 14 day before testing. Sodium lignosulfonate is adhesive material which physically binds soil particles together and steel slag mechanically improves gradation of soil and makes bonds with clay particles. Moreover steel slag is waste material. These both materials unlike cement are non-toxic and environment friendly. The results show that unconfined compressive value, maximum dry density of soil increases whereas OMC of soil decreases highly.
