ABSTRACT:
A method is provided for accurately and easily measuring properties of sand. This method includes the steps of measuring contraction properties of the sand, determining a molding parameter for molding a test piece of the sand having a known size based on the measurements of the contraction properties before the test piece is press-molded, press-molding the test piece by compacting a feed of the sand in accordance with the molding parameter, and measuring the properties of the sand by measuring properties of the test piece.
