Abstract
The invention concerns a self-levelling concrete and a method for making a structural part from said concrete. The concrete which comprises aggregate and solid particles with size grading not more than 12 mm, comprises a superplasticizer which is a compound containing a least an amino-(dialkylene phosphonic) group and at least a polyalkylated chain, or one of its salts. The method is implemented by advantageously pumping the concrete using one or several immersion tubes with their injecting end at a lower level than the framework.
