High-performance concrete: from the laboratory to practical utilization

Fig. 1. The bridge of Re Island. He de Re Bridge: this was the first major application of HPC to a bridge in France.

The main objective was to accelerate form release (precast segments) and to improve the durability of the concrete in the sea. Thanks to the 15 MPa at 10 hours that was obtained, it was possible to produce up to 150 precast segments per month, allowing construction in record time.
