摘要
用正交试验方法研究了不同硫铝酸钡钙(C2.75B1.25A3-S)矿物含量的阿利特(C3S)-硫铝酸钡钙水泥组成与性能.研究结果表明:阿利特和硫铝酸钡钙矿物可以在同一熟料体系中共存;硫铝酸钡钙矿物的最佳含量为8.0%(质量分数,下同);阿利特-硫铝酸钡钙水泥熟料最佳矿物组成为:8.0%C2.75B1.25A3-S,61.6%C3S,14.7%C2S,5.1%C3A,10.5%C4AF;在最佳矿物组成条件下制备的阿利特-硫铝酸钡钙水泥的1,3,28 d抗压强度分别为39.8,77.5,85.0 MPa,展现了良好的早期力学性能.借助于XRD和SEM-EDS分析,研究了阿利特-硫铝酸钡钙水泥熟料的组成和结构.
The clincker composition and performance of alite-calcium barium sulphoaluminate cement with different content of C2.75B1.25 A3S were studied by orthogonal test. The results show that alite and calcium barium sulphoaluminate can coexist in a clincker system. The optimal content of C2.75B1.25A3S is 8.0%. The optimal composition of the clinker mineral system is confirmed with 8. 0% C2.75 B1.25 A3S, 61. 6% C3S, 14. 7% C2S, 5. 1% C3A, 10. 5% C4AF. The compressive strength of alite-calcium barium sulphoaluminate cement at 1,3,28 d are individually 39.8, 77.5, 85.0 MPa, which shows excellent performance of early strength.
