A method for obtaining a composite comprising a cross-linked acrylic polymer and at least one inorganic aggregate, the method comprising the steps of:
- a. mixing a plurality of acrylic monomers, at least one cross-linker, and a radical initiator, thereby obtaining a mixture of the cross-linked polymer;
- b. adding an inorganic aggregate to said mixture, the inorganic aggregate and/or mineral being present at a concentration of 80% to 95%, by weight of said mixture, and
- c. curing said mixture at a temperature of above 80° C., thereby obtaining said composition.
