Mechanical Characteristics of Inorganic Binder Stabilized Iron Tailings
As the largest solid waste in China, iron tailings have brought a huge impact and potential safety hazard to resources, environment and land. In this paper, using the stress-strain controlled soil mechanics tri-axial apparatus, the author researched the mechanics performance of the cement stabilized iron tailings in the laboratory. The result shows: Along with the increase of the cement dosage, stabilized material strength has improved significantly; Under the confining pressure from 300 kPa to 500 kPa, the increase of confining pressure is proportional to the strength of stabilized material. Moreover, lower cement content (3%-5%) of stabilized material, its stress-strain curve is similar to those of clayey soil, it has clear plastic yield characteristics; on the contrary, higher dosage of cement stabilized material (7%-9%), the plastic reduced and strength increased.
