Factors influencing strength development of concrete containing silica fume
Existing data on the relationships between temperature, pozzolanic activity and cement hydration are reviewed with particular emphasis on condensed silica fume (CSF)-ordinary Portland cement blends. CSF concrete with a range of fume contents has been cured a two temperatures (20 degrees C and 50 degrees C) for periods up to 91 days. Strength development and relative strength are considered in the relation to temperature, cement hydration and pozzolanic action. The observed results establish that relative strength varies directly with CSF content and that the strength enhancement at early curing periods, which is achieved by increase in curing temperature, is a result of increasd reaction rate between Ca(OH)2 and CSF.
