Abstract

order to study the influences of different thermal curing methods on volcanic activity and mechanism of rich-silicon iron ore tailing powder (IOTP). Four different specific surface area of IOTP cured in different conditions were tested, at the same time, the strength, pore size distribution and hydration product were measured.Test results show that IOTP do not have activity cured by room temperature, it shows different degrees of volcanic activity cured by thermal conditions, especially in autoclaved condition. Hot-wet curing systems can obviously reduce the porosity and pore diameter size of IOTP mortars, improve the compactness of hydration products at the same time, the autoclaved curing systems is the best. Cured in autoclaved condition, the strength of IOTP mortars is the highest when the dosage of IOTP is 10%, but the pore size distribution is the best when the content of IOTP is 30%.
