<p>The invention relates to a process for obtaining cellular concrete products without autoclaving, used in constructions for making inside and outside non-bearing walls. A primary mixture of sand, cement and water is introduced into a free fall-type mixer, at a rotative speed of 11...26 rot/min, wherein, through an injector-type pipe, coupled to an installation for preparing the mechanical foam, there is injected a proteinic-type foaming agent in continuous jet for 60...180 sec, with a flow rate of maximum 0,750 kg/min3 of cellular concrete. After the injection, the mixture is moulded into moulds.</p> |
