摘要：

Formation and coexistence of tricalcium silicate (C3S) and calcium sulphoaluminate (C(4)A(3)(S) over bar) minerals in Portland cement clinker containing calcium sulphoaluminate were investigated. The f-CaO content, mineral composite and formation of mineral in the clinker were analyzed respectively by chemical analysis, differential scanning calorimetry(DSC) and X-ray diffraction. The results show that, adding a suitable amount of BaO can improve the burnability of raw meal and promote the f-CaO absorption. Tricalcium silicate and calcium sulphoaluminate minerals can form and coexist in clinkers at 1 234-1 317 degrees C by the addition of BaO to the raw meal. A suitable amount of BaO expanded. the coexistence temperature of two minerals by 58 degrees C.
