Abstract

Abstract

Using vanadium-titanium magnetite tailings for preparation of geopolymer can not only reduce pollution of the tailings, but also realize the efficient utilization of the tailings. The geopolymer was prepared from vanadium-titanium magnetite tailings in Chengde by mechanical activation process. The effect of activation time on the particle size and microstructure of the tailings and the compressive strength of the geopolymer products were investigated. The results show that prolonging the activation time can reduce the particle size and destroy the crystal structure of the tailings, which can increase the leaching concentration of active silicon and aluminum in the tailings and improve the compressive strength of the geopolymer. At the activation time of 3 h, mass ratio of tailings to kaolin of 6∶4, Ca(OH)₂ and Na₂SiO₃ addition respectively of 10%, ratio of mortar to sand of 1∶1.5 and liquid-solid ratio of 0.20, the geopolymer with the 28-day compressive strength up to 50 MPa can be obtained. The leaching concentration of heavy metal ions in the sample meets the national standard. The amorphous aluminosilicate gel phase is tightly bonded with a small amount of zeolites, endowing the products with a high compressive strength.
