Keywords： barium oxide

Formation and coexistence of tricalcium silicate(C_3S)and calcium sulphoaluminate (C_4 A 3(S))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 ℃by the addition of BaO to the raw meal.A suitable amount of BaO expanded the coexistence temperature of two minerals by 58℃.
