Hydration Reaction of Cementitious Materials Prepared with Molybdenum Tailings

Yanqing Di / Xiaowei Cui / Ning Nan / Chunsheng Zhou

Cementitious materials is prepared with blended powders including molybdenum tailings, slag, clinker and gypsum. The effect of molybdenum tailings proportion on strengths and hydration products of molybdenum- tailing-based neat paste are studied. The results indicate that the compressive strength of neat paste decreases gradually with the increase of molybdenum tailings proportion. The relatively appropriate molybdenum tailings proportion in cementitious materials is 30%. The compressive strength of molybdenum- tailing-based neat paste is high up to 43.10 MPa cured at 28 days. The ground molybdenum tailings have a certain reactivity in the studied system. The hydration products of cementitious materials prepared with molybdenum tailings are mainlyettringite (AFt) and C-S-H gel.
