ABSTRACT
The use of fly-ash or blast furnace slab to partially replace OPC in concrete is now commonplace. Changes in the time-dependent properties of concrete due to the addition of these cement replacement materials may be significant and hence must be accurately assessed. The existing literature related to the effects of GGBFS on creep and shrinkage is scarce. Pane & Hansen (2002) found that tensile creep and shrinkage is decreased in concrete containing granulated slag. Li et al. (2002) performed tests to measure tensile creep and shrinkage starting from the age of 3 days. They found that tensile creep and drying shrinkage decrease by the addition of GGBFS, however autogeneous shrinkage was higher when GGBFS was used.
