Abstract
A fast hydraulic binder comprising cement, at least one first superplasticizer, a calcium salt, and at least one second superplasticizer different from the first superplasticizer and comprising a main chain and pendant groups connected to the main chain adapted so as to separate from the main chain in a basic medium, wherein the result is that the second plasticizer has a fluidifying action which increases at least temporarily over time in a basic medium.
