Abstract

Molybdenum tailings are the waste of molybdenum extracted from refined molybdenum ore. Because of its potential gelling, it can be prepared as a cementing material instead of cement. In order to improve the pozzolanic activity of molybdenum tailings, mechanical activation method was used to discuss the effect of activation time on its activity, and the activation effect was judged by particle size analysis and other tests. Using calcium oxide and sodium carbonate as composite activator, molybdenum tailings were used to prepare composite cementing material. The effects of activator content, tailing dosage and activation time on mechanical properties and hydration mechanism of the material were evaluated. The results show that mechanical activation can improve the activity of molybdenum tailings, which proves that it can be used as a cementing material instead of cement, which is conducive to the utilization of tailings waste.
