A Study on the Strength Performance According to Blast Slag Replacement of Fireproof Mortar using Oyster Shell Aggregate

초록
In the case of B / a 1: 3, the intensity when the substitution rate increased to 15% showed a tendency to decrease, but it turned out that the strength increased at the substitution rate of 20%. In the case of B / a 1: 4 and 1: 5, it was found that when the substitution rate at the substitution rate of 10% was the highest and the substitution rate increased further, the strength was reduced. However, since the test body does not exist at the age of 3 days and the age of 7 days at the substitution rate of 0%, there is no specimen, so blast furnace slag binder substitution for increasing strength of refractory mortar is judged to be meaningless.
