摘要：

The research presented in this paper was intended to clarify the nature of concrete strengthening in the presence of silica fume. For this purpose, compressive strength development of high strength concrete and its paste-matrix was investigated. Carbon black was introduced as an alternative microfiller to silica fume. The results indicated that carbon black was effective in modifying the basic concrete-matrix strength relationship to an extent similar to that obtained by silica fume. It is suggested that the mechanism by which silica fume affects the concrete behaviour is of a physical origin and is based on microfiller effect, prior to its action as a pozzolanic material. The microfiller effect is of greater significance to strength enhancement.
