| 摘 要： | 研究了石膏对贝利特-硫铝酸钡钙水泥强度和硬化浆体结构的影响.结果表明:贝利特-硫铝酸钡钙水泥熟料的矿物组成主要有C3S、C2S、C,A、C4AF和C2.7B1.25A3S;当水泥中石膏掺量为10%时,贝利特-硫铝酸钡钙水泥的3d、7 d、28 d和90 d抗压强度分别达到了45.0、61.9、82.1和85.6 MPa;贝利特.硫铝酸钡钙水泥的水化产物主要有AFt、Ca(OH)2、C-S-H凝胶等,随石膏掺量的增加,AFt的数量逐渐增加,水化后期的Ca(OH)2数量逐渐减少.用XRD和SEM来分析硬化水泥浆体组成和结构.

| Abstract: | The influence of gypsum on compressive strength and performance of hardened paste of belite-barium calcium sulphoaluminate cement was studied. The results showed that mineral phases of belite-barium calcium sulphoaluminate cement clinker were C3S,C2S,C3A,C4AF and C2.75B1.25A3S. When gypsum content is 10%,the compressive strengths at 3 d,7 d,28 d and 90 d curing ages are 45.0,61.9,82.1 and 85.6 MPa. The hydration products of belite-barium calcium sulphoaluminate cement are mainly AFt,Ca(OH)2,C-S-H gel. With ... |
