NEW REACTIVITY CONTROLLED CALCIUM ALUMINATE TECHNOLOGIES FOR DEFLOCCULATED CASTABLES

摘要

The role of calcium aluminates in refractory castables has evolved from that of a fundamental binder largely dictating castable placing properties in regular conventional concretes to more of a reactive chemical in deflocculated castables. Stable placing properties together with the targeted installed characteristics of deflocculated castables can only be achieved if the interactions between the various components of the matrix are managed along with the intrinsic variability of each of these components, hi this regard, significant progress has been made with a continuous evolution of calcium aluminate binders towards products displaying significantly reduced variation.
