    摘要: Disclosed is an unfired refractory composition comprising a refractory aggregate and a binder for the refractory aggregate, in which the binder comprises a water-soluble or water-dispersible siliceous binder in an amount of 1 to 20% by weight based on the refractory aggregate, a carbonizable organic binder in an amount of 2 to 15% by weight based on the refractory aggregate and a phosphate type hardening agent in an amount of 0.5 to 20% by weight based on the refractory aggregate.This refractory composition is moldable and hardenable at normal temperatures, and has an excellent mechanical strength not only at relatively low temperatures below about 500.degree. C. and high aggregate-firing temperatures but also intermediate temperatures between these low and high temperatures. Accordingly, if this refractory composition is used as a liner for a furnace or the like, break-down of the liner in the intermediate region between the inner surface side and the outer surface side is effectively prevented, resulting in prominent elongation of the life of the liner. Furthermore, this refractory composition has a long pot life in the kneaded state and is excellent in the working property and processability.
