摘要：
The creep behavior of refractory lining is crucial, which is determined by both material and masonry structure. In this paper, the effect of temperature and stress on the creep behavior of fireclay refractory and brick-mortar couplets were studied by using advanced uniaxial compression creep test. The creep behavior of fireclay re-fractory is sensitive to temperature due to formation of liquid phase. Meanwhile, the closure of discontinuous interfaces contributes to the increase of compressive creep in couplets. The masonry specimen with two mortar layers deforms less than that with one mortar layer, as thermal stresses are moderated by the additional mortar layer.
