oa Civil Engineering = Siviele Ingenieurswese - Some properties of high-slag concrete

  • ISSN : 1021-2000



A series of workability, compressive strength, shrinkage and creep tests on high-slag concrete, ie concrete containing large percentages of milled granulated blast-furnace slag in the binder component, have been carried out. The results indicate that the workability of high-slag concrete is superior to that of portland cement concrete and that, even at high slag/cement ratios, the strength of the resulting concrete is not much reduced. The results also show that the shrinkage and creep of high-slag concrete are greater than the corresponding values for portland cement concrete but can be reduced by adopting a mix design procedure which takes cognizance of the superior workability of highslag concrete.
