摘要
利用ＳＥＭ研究了在掺与不掺石膏的条件下，新水泥熟料矿物３ＣａＯ·３Ａ１＿２Ｏ＿３．ＢａＳＯ＿４的水化产物及其浆体结构。纯３ＣａＯ·３Ａ１＿２Ｏ＿３．ＢａＳＯ＿４水化很快，具有致密的浆体结构，从而具有很高的抗压强度。掺入石膏后，３ＣａＯ·３Ａ１＿２Ｏ＿３．ＢａＳＯ＿４的水化反应受到阻碍，使浆体孔隙率上升，强度下降。含钡硫铝酸盐水泥不应与石膏混合使用。
The hydration of a new cementitious mineral 3CaO·3A1_2O_3·BaSO_4 have been investigated with SEM in the presence or in the absence of gypsum.Pure 3CaO.3A1_2O_3· BasO_4 hydrates quickly and has dense pastestructure.A high compressive strength is obtained. The hydration reaction of 3CaO . 3A1_2O_3 . BaSO_4 is hin-dered in the presence of gypsum. The paste porosity of 3CaO·3A1_2O_3.BasO_4 with gypsum is high and itsstrength is low. It is unsuitable for using Ba-bearing sulphoaluminate cement together with gypsum.
