The invention relates to the production of concrete. The method for production of concrete comprises two successive and separate steps. In a first step, the sand, hydraulic binder and water are mixed in a mixer in order to obtain a concrete batch. Then, in a second step, the batch thus obtained, on the one hand, and the aggregate, on the other hand, are emptied into at least one second movable mixer in which mixing is carried out during transportation in order to form a concrete which can be poured out at the site of use. <IMAGE>
