Model formulations as shown in Table 1 have been used to determine the TSR.As reference formulations an A-MA（A-MA-CAC6）and an A-M castable（A-M-CAC6-1S），both bonded with 6%Secar71（CAC）have been chosen.The impact of CMA on TSR of the A-MA castable has been evaluated with the formulation A-MA-CMA18（18%CMA）.In the A-M system CMA has been tested with the formulation A-M-CMA-1S（18%CMA and 1%Si O2）.The CMA containing formulations have equal chemistry and equal mineralogy after firing compared to their references A-MA-CAC6 and A-M-CAC6.But they have a different distribution of spinel，calcium aluminate phases and micro-pores which gives them their superior slag penetration resistance.Detailed information about the composition of CAC and CMA and the microstructures，penetration and wear resistance of castables formulated with both binders can be found in W9hrmeyer，et al.[2].
