ABSTRACT
Very dry, precasting, concrete. (Water control monitored by an ohmmeter) Concrete containing different types of fibres. Micro-silica concrete. (eg. for the Great Belt bridge project) High strength concrete. (eg. the Densit type) Flyash concrete. Lightweight concrete. (Inorganic and polystyrene aggregate) The experience obtained suggests that a successful solution of the problem of
mixing some of the special concretes has to begin with the storage and proportioning systems.
