The clincker composition and performance of alite-calcium barium sulphoaluminate cement with different content of C_(2.75)B_(1.25)A_3 were studied by orthogonal test.The results show that alite and calcium barium sulphoaluminate can coexist in a clincker system.The optimal content of C_(2.75)B_(1.25)A_3 is 8.0%.The optimal composition of the clinker mineral system is confirmed with 8.0%C_(2.75)B_(1.25)A_3,61.6%C_3S,14.7%C_2S,5.1%C_3A,10.5%C_4AF.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.
