Production of improved synthetic stone bodies with controlled properties

Claim 1

IN THE PRODUCTION OF A CONCRETE OR THE LIKE CAST BODY, THE METHOD OF PRODUCING A SYNTHETIC AGGREGATE FOR PRODUCTION OF SUCH CONCRETE OR THE LIKE WHICH COMPRISES COMPRESSING A PULVERULENT DRY MASS OF HYDRAULIC CEMENT COMPRISING ESSENTIALLY THE SYSTEM CAO-SIO2 AT A PRESSURE BETWEEN ABOUT TWENTY TONS AND ABOUT TWO HUNDRED TONS PER SQUARE INCH TO PRODUCE A FORM-RETAINING SLUG, CRUCHING THE SLUG SO FORMED TO PRODUCE RANDOM SHAPE, GRADUATED SOLID FRAGMENTS AND HYDRAULICALLY CRYSTALLIZING THE SAID SOLID FRAGMENTS IN AT LEAST ABOUT THREE PARTS BY WEIGHT OF WATER FOR NOT LESS THAN ABOUT TWENTY-FOUR HOURS WHILE AGITATING THE MIXTURE TO CONTROL THE HEAT THEREOF TO PREVENT CRACKING, TO THEREBY PRODUCE AGGREGATE BODIES SUBSTANTIALLY MORE INERT AND HAVING GREATER SPECIFIC GRAVITY, HARDNESS, COMPRESSION RESISTANCE AND TENSILE STRENGTH THAN HYDRATED NEAT CEMENT, TOGETHER WITH THE PROPERTY OF FORMING A CONTINUOUS INTERCRYSTALLINE STRUCTURE WITH A HYDRATED CEMENT MATRIX.
