Abstract
A microcapsule, in particular of spherical shape, having a hollow capsule core encased by a capsule shell, characterized in that the capsule shell is at least partially made of hydrated cementitious material. A method for the production of a microcapsule includes the steps of: a) preparing of a suspension of particulate cementitious material in a solvent b) preparing a dispersion by mixing the suspension of step a) with an immiscible fluid so that (i) the suspension is present as a dispersed phase in the fluid as a dispersion medium or that (ii) the fluid is present as the dispersed phase in the suspension as the dispersion medium, such that the particulate material of the suspension adsorbs at least partially at a phase boundary between the fluid and the suspension, and c) allowing the particulate material adsorbed at the phase boundary to hydrate with the formation of an individual microcapsule.
