High strength mortars containing condensed silica fume
AbstractA silica fume and a superplasticizer have been added to an ordinary easily flowing mortar composition. The optimal amounts of those constituents have been determined in order to obtain the maximum compressive strength for a constant workability. Large contents of silica fume and superplasticizer are needed (silica/cement=0.40 and superplasticizer/ce cement=2.4% in dry weights). The compressive strengths are approximately twice higher at 2,7 and 28 days as compared to the reference mortar. The drying shrinkage is slightly increased and the hydration kinetics is highly modified.
