Experimental Research on Dry Shrinkage Performance of Ferrous Mill Tailings Stabilized with Inorganic Binding Materials

Article Preview

Abstract:

Dry shrinkage performance of ferrous mill tailings stabilized with inorganic binding materials with the optimal ratio is studied through laboratory test. The curves of water loss-time and dry shrinkage strain-time are obtained. The comparisons to that of soil-lime are also made. It shows that the largest for water loss ratio and dry shrinkage strain is soil-lime, its dry shrinkage performance is the worst. The dry shrinkage strain of ferrous mill tailings stabilized with lime added a small amount of cement is increased, however, the compaction is increased and the amount of lime and cost is greatly reduced. The dry shrinkage performance of those materials: ferrous mill tailings stabilized with lime the best, then ferrous mill tailings stabilized with lime (cement), ferrous mill tailings stabilized with cement, soil-lime.
