The flow ability, strength development, and hot strength （ HMOR ） were investigated. Different types of additives were used for the CA-670 bonded castables. The results show CA-670 provides a good workability for each type of＂ castables. CA-670 displays a good compatibility with different types of additives. Testing on different batches of CA-670 shows good reproducible properties in each castable, which manifests good consistency and reliability of CA-670.展开更多
