摘要：
A microcapsule (10, 20), in particular of spherical shape, comprising a hollow capsule core (11, 21) encased by a capsule shell (12, 22), is characterized in that the capsule shell (12, 22) is at least partially made of hydrated cementitious material. Furthermore, a method for the production of microcapsule comprises the steps of: a) preparing of a suspension (100) of particulate cementitious material (111) in a solvent (125) and b) preparing a dispersion (200) by mixing the suspension (100) of step a) with an immiscible fluid (130), so that (i) the suspension (100) is present as a dispersed phase in the fluid (130) as a dispersion medium or that (ii) the fluid (130) is present as the dispersed phase in the suspension (100) as the dispersion medium, such that the particulate material (111) of the suspension adsorbs at least partially at a phase boundary between the fluid (130) and the suspension (100), and c) allowing the particulate material (112) adsorbed at the phase boundary to hydrate with the formation of an individual microcapsule (115).
