Abstract:The mechanical and structural properties of mortars containing silica fume were studied. Mortars containing 5 and 10 percent active silica additive were made. Mortars without silica fume (standard mortars) were also prepared. A first set of mortar specimens was cured entirely in water. A second set of mortars was cured in air. The third was immersed in water and then subjected to alternating cycles of storage in water and air. The results show a very close relation between the conditions of the mortars' curing and their mechanical properties. The flexural strengths of mortars containing silica fume, subjected to variable curing conditions, show periodic increases and reductions. SEM observations confirmed the relations found in the flexural strength tests.
