Hydraulic concrete - Implementation - Concreting and tightening

This third section deals with current concreting problems. Aspects of plasticity control are discussed in practical terms on the worksite. How can we distinguish a random problem from a functional maladjustment of the concrete? And, in the case of one-off incidents, how to determine the real causes.

The pouring of concrete into the formwork is then dealt with, including the different situations likely to be encountered in the case of concrete pumping, then tightening by vibration for common concretes. The special case of self-compacting concrete is also discussed.

Finally, the concreting of deep foundations is dealt with separately, given the specific features of the fluid, non-vibrating concretes used.
