Beschreibung
Zusammenfassung:	The invention provides a particulate material for the production of a cement foam which material comprises particles comprising, attached to the particle surface, a surfactant which renders the particles hydrophilic, the surfactant comprising a moiety which is hydrolysable under alkaline conditions, which surfactant, after loss of the moiety by alkaline hydrolysis, renders the particles partially hydrophobic
