The present invention relates to a silo (100) for the production of concrete, which comprises, inter alia, a main chamber (1) for storing a first, preferably powdery, component and at least one secondary chamber (2) for storing a second, preferably liquid, component. The present invention also relates to a plant (1000) which comprises the silo (100) according to the invention and further comprises a mixer (150) in which the first and the second components can be mixed with one another as aqueous mixtures, in particular continuously, to form concrete, in particular to form lightweight porous concrete, and the finished concrete can be removed therefrom, preferably continuously. The silo (100) according to the invention or the plant (1000) according to the invention enable the production of concrete adapted to the ambient conditions of the silo or the plant, wherein the quantities of the components can be individually dosed. A further subject matter of the invention is a method for producing concrete, in particular lightweight porous concrete also known as foamed concrete, in the plant according to the invention, and the use of the silo according to the invention for producing concrete, in particular lightweight porous concrete.
