Abstract: The present invention relates to a (meth)acrylic composition suitable for (meth)acrylic polymeric compositions and (meth)acrylic polymeric composites, its method of preparation, its use and obtained (meth)acrylic polymeric compositions and (meth)acrylic polymeric composites. In particular the present invention relates to a (meth)acrylic composition that is crosslinked once polymerized and that is suitable for (meth)acrylic composites and more particular for reinforcing elements or fibre reinforced polymer (FRP) rebars. More particularly the present invention relates to a (meth)acrylic composition suitable for producing reinforcing elements or FRP rebars, preparing such a (meth)acrylic composition, composite reinforcing elements or rebar comprising it after polymerization and method of preparing such a composite reinforcing elements or FRP rebar. The present invention also relates also to the use of such a (meth)acrylic composition and the use of reinforcing elements or FRP rebars for concrete.
