Abstract: A self-setting porous cement foam includes a protein foam as the structuring agent and has pores when set and a water absorption coefficient of between 0.5 and 7 kg/(m2·h0.5). A foam gun for producing a structure-imparting foaming component of a cement foam has a tubular design, an inlet orifice for a liquid and an inlet orifice for a gas or gas mixture. At least one first mesh is disposed downstream of the inlet orifices for the liquid and the gas or gas mixture and at least one second mesh is disposed in front of an outlet orifice from the foam gun. Disposed in the space between the at least one first mesh and the at least one second mesh is at least one foaming element having baffle structures specifically designed to create a turbulent flow between the at least one first mesh and the at least one second mesh.

Abstract: The invention relates to a self-setting porous cement foam (2) comprising a protein foam as the structuring agent, the cement foam (2) having pores when set, and the cement foam has a water absorption coefficient of between 0.5 and 7 kg/(m2·h0.5).
