Title: Prediction of Strength Development for Silica Fume Concrete
Author(s): Malvin Sandvik and Odd E. Gjorv
Publication: Special Publication
Appears on pages(s): 987-996
Keywords: aggregates; compressive strength; concretes; hydration; pozzolanic reactions; silica fume; strength; Materials Research
Abstract:Silica fume has an accelerating effect on the early hydration of portland cement. Also, silica fume reduces the retarding effect of lignosulfates. At standard curing conditions, the contribution to strength from the pozzolanic reaction takes place primarily at 5 to 7 days. As a result, existing equations for prediction of strength development based on pure portland cement are no longer valid for concrete with silica fume. Some new equations for concrete with various contents of silica fume are presented.
