Normal tap water is usually used as the water, it being understood that it is also possible to use distilled or deionized or purified water. Optionally, other additives for mixing with the powdered cement in the first mixing section 3 can be abandoned, as indicated by a dashed arrow Θ in F'ig. 1 is indicated wherein at least some of the additives can also be added in liquid or dispersed form.
It is possible that the mixing of the pulverulent constituents takes place before the addition of the water according to arrow 7, that is to say that the cement for the production of the cement foam 2 has already been added to these hit solids or processing aids and, if appropriate, premixed these pulverulent components.
The mixing section 3 is designed as a paddle mixer or plow blade mixer, whereby other mixer types, such as e.g. Free fall mixer, can be used. However, the former mixer types have the advantage that less water has to be added - the goal is to use as little water as possible - and that the energy consumption per m3 of cement is relatively low. In addition, the risk of the mixer sticking to these rounded shapes can be reduced. In particular, this mixing section 3 may comprise mixing elements 9, which are arranged offset in the radial direction on a mixing path shaft 10. It can be arranged in the mixing section 3, for example, between 2 and 20 mixing elements 9. N2012 / 04300 14/06/2012 11:46
