Abstract:
The effect of condensed silica fume on the strength deve-lopment in concrete was studied by replacement of 0, 5,10, and 20% cement by silica fume. No admixtures was used. For all the mixes,about the same strength was obtained up to 7 days. From then on,the mixes with silica fume produced an increased strength development compared to that of pure cement. At a partial replacement of cement by 20%, the compressive strength at 28 and 90 days was increased by 43 and 55%, respectively, with respect to the strength at 7 days.
