【摘要】：以石煤提钒尾矿细粉、碳酸钙、粘土和铁粉为原料,在不同煅烧条件下制备了不同配比的产物,并研究了其性能。结果表明:(1)产物的主要成分为硅酸三钙、硅酸二钙、铁铝酸四钙和铝酸三钙,符合水泥熟料的化学组成;(2)熟料煅烧温度为1400℃,粘土掺加量为8%时的方案最优。
[Abstract]:Using fine powder, calcium carbonate, clay and iron powder from vanadium tailings extracted from stone coal as raw materials, different ratio products were prepared under different calcination conditions, and their properties were studied. The results show that: (1) the main components of the product are tricalcium silicate, dicalcium silicate, tetracalcium ferrate and tricalcium aluminate, which accord with the chemical composition of cement clinker, (2) the clinker calcining temperature is 1400 鈩，
