Method for manufacturing split-faced concrete pieces, a split-faced concrete piece, and means for applying the method

摘要

The invention relates to a method for manufacturing a split-faced concrete piece, a split-faced concrete piece, and a means for applying the method. During casting, a reactive material is added to the concrete to form the desired split-faced surface, the reactive material being of a type that causes a splitting pressure in the concrete piece, due to expansion or some other reaction.
