Silica fume has for some time been used in various applications to improve the overall quality of concrete both in the fresh and the hardened state. It has been used extensively to improve the durability of concrete. It is an extremely efficient repair material given its thixotropic properties and its use in roller compacted concrete has been successful. The use of silica fume in abrasion resistant concrete is an economically attractive one and its applications in offshore structures have also been successful. In recent years, silica fume has been used in the production of high strength concretes. At the present state of the art, field placeable concretes with compressive strengths in excess of 100 mpa have been produced successfully only when silica fume was used as a partial replacement for portland cement. This is a survey of some of the most recent developments, both in research and in actual applications, on the production, behaviour and properties of concretes containing silica fume. The ways in which silica fume may affect the properties of the fresh and hardened concrete are examined and related to high strength concretes.Read More
