Abstract: This paper is the point of view of a French SCC user which sometimes produces its own SCC on housing or civil engineering job sites. It deals mainly with cast in place concrete (SCC development is much faster in the precast industry). Some opportunities and bottlenecks for SCC development in cast in place applications are exposed, based on some practical examples. In a first part, the great technical potential of SCC is illustrated: easiness of placing (allowing to build difficult concrete structures), surface finish quality, productivity enhancement and quality of hardened concrete. Other benefits when using SCC are not developed even if they are quite important and may be a sufficient reason for choosing SCC: noise reduction (for the workers and for the site surroundings) and improvement of working conditions (reduction of physical strain). Despite all the opportunities listed, SCC development for cast in place applications is quite slow (about 3% of the ready-mixed concrete in France) and some possible explanations for this are given in a second part: need for high quality concrete materials, in some cases (high vertical elements) need for special formwork, insufficient accuracy of production equipment, stringent quality control requirements and lack of specific standards. Soon, some of these drawbacks will be minimized and SCC development will go on and increase the possibilities offered in terms of architectural design.
