The subject matter of the invention is a curable composition for use as bone cement, in particular for augmentation of osteoporotic bone tissue, comprising at least one organic polymer and at least one monomer for radical polymerisation, at least one particulate inorganic additive having a BET surface of at least 40 m2/g, whereby the additive comprises covalently bound hydroxyl groups, whereby the composition further comprises at least one fatty acid ester or a mixture of fatty acid esters. Another subject matter of the invention is the use of said composition for augmentation of osteoporotic bone tissue and particularly preferably for vertebroplasty, kyphoplasty, and augmentation of drill holes in osteoporotic bone tissue, as well as a kit for producing said composition.
