This is a Ph.D. dissertation. SCC, Self-Compacting Concrete, was initially developed in Japan in 1988 at the University of Tokyo by Prof. Okamura and his colleagues. SCC has been applied in many actual construction projects since the early 1990's. However, the SCC technology had not been spread on a world-wide scale when the author started his guest researcher-ship at Delft University of Technology in 1996. SCC was a topic of interest in the Dutch concrete industry.

In order to fulfill the interest of the Dutch concrete industry, the first stage of the project aimed at verifying the producibility of SCC in a laboratory of a Dutch ready-mixed concrete plant applying Dutch local materials. Within the scope of this work, a recommendation for a Dutch prototype SCC mixture and a quality control method was aimed at. After the development of the prototype, the research focused on the application of very fine mineral admixtures, so called "microfillers" as a material for SCC. An investigation of the effect of coal gasification fly ash (CFGA), which is a very fine and round-shaped fly ash which new appeared on the Dutch market, was carried out in comparison with the performance of other microfillers, like silica fume and micronized fly ash.

Contents include: Introduction, Survey of Literature, Development of the SCC in the Netherlands, Influence of Silica Fume, Micronized Fly Ash and Coal Gasification Fly Ash on the Fresh and Hardened Properties of SCC, Influence of Mixing Efficiency and Admixtures on the Properties of Fresh SCC, Influence of Mixing Efficiency and Chemical Admixtures on the Properties of Flowable Cement Paste, Conclusions and Suggestions.
