Method for producing a concrete by mixing a mixture of products, i.e., firstly, fines such as cement and filler in particular, and granulates such as sand and gravel in particular and, secondly, a nominal quantity of liquid (Qn), particularly water and adjuvants, in a mixer, said method being based on the principle of real-time monitoring of the consistency of the mixture during the mixing of the products, and requiring a prior determination of a reference curve characterised in that said reference curve, or fluidity curve (Cf), is dependent and specific, firstly, with respect to said mixer, but also, secondly, with respect to an order of introduction of the products into the mixer, and with respect to a total quantity of loaded products, independent however of the composition of said mixture, said fluidity curve (Cf) being obtained by producing a plurality of batches of concrete of different compositions, of the same volume, according to the same order of introduction of the products into the mixer, and by identifying for each curve the fluidity point (Pf), said fluidity point (Pf) being the point of the consistency curve corresponding to the sudden transition between a highly cohesive state of the mixture to the state of the mixture, described as a granular suspension, wherein the capillary forces have suddenly disappeared, said fluidity curve (Cf) being the curve passing via said fluidity points (Pf), defining two consecutive phases of the mixture during mixing in the geometric space representative of the consistency of the mixture in relation to the mixing time, i.e. a first phase, described as cohesive, wherein the mixture is cohesive due to the magnitude of the capillary forces, and a second phase, described as a granular suspension also known as uniform concrete, wherein the capillary forces have suddenly disappeared, method wherein: - the mixer is loaded with a quantity of products similar to that used for the determination of the fluidity curve (Cf), optionally of equivalent composition, according to an order of introduction of the products into the mixer similar to that used for determining said fluidity curve (Cf), - said products are mixed by measuring the consistency (Mc) of the mixture, and the progression of the consistency curve (Cc), representing the value of the consistency (Mc) of the mixture in relation to the mixing time, is monitored in real time, - the fluidity point (Pf), defined by the intersection of the consistency curve (Cc) with the fluidity curve (Cf) is determined, directly and/or by anticipation, and, if applicable, the uniform concrete information is inferred on passing the fluidity point, - the deviation (Δ 1) between the actual quantity of liquid (Qr) in the mixture and the nominal quantity of liquid (Qn), after calibrating the corresponding concrete recipe on the basis of the uniform concrete information and/or on the basis of an estimation of the passage of the fluidity point (Pf) and, optionally, a corrective measure is applied to the production of the concrete. - the mixer is loaded with a quantity of products similar to that used for the determination of the fluidity curve (Cf), optionally of equivalent composition, according to an order of introduction of the products into the mixer similar to that used for determining said fluidity curve (Cf), - said products are mixed by measuring the consistency (Mc) of the mixture, and the progression of the consistency curve (Cc), representing the value of the consistency (Mc) of the mixture in relation to the mixing time, is monitored in real time, - the fluidity point (Pf), defined by the intersection of the consistency curve (Cc) with the fluidity curve (Cf) is determined, directly and/or by anticipation, and, if applicable, the uniform concrete information is inferred on passing the fluidity point, - the deviation (Δ 1) between the actual quantity of liquid (Qr) in the mixture and the nominal quantity of liquid (Qn), after calibrating the corresponding concrete recipe on the basis of the uniform concrete information and/or on the basis of an estimation of the passage of the fluidity point (Pf) and, optionally, a corrective measure is applied to the production of the concrete.
