Method and device constraints relaxation at the end of compacting oedometer a mixture of aggregate and binder

THE INVENTION CONCERNS A PROCESS FOR RELAXATION OF STRESS SIDE, END OF SHAPING BY COMPACTION BLOCK IS AN AGGREGATE AND BINDER (SUCH AS CARBON PASTE) ON WHICH APPLIES AN STRESS IN HOME uniaxial MOLD WITH A RIGID BOTTOM AND FOUR SIDE WALLS. FROM THE METHOD, THE END OF cOMPACTION, KEEPS ON, BY cOMPACTION AXIS RESIDUAL STRESS BETWEEN 5 AND 200 AND pREFERABLY BETWEEN 10 AND 50KILOPASCALS THEN ON REJECTED SOME mILLIMETERS AT LEAST TWO OF SIDE WALLS OF MOLD AND THEN ON DELETE STRESS HOME AND ON EXTRACT MOLD BLOCK. STRESS RESIDUAL IS MAINTAINED FOR A PERIOD BETWEEN 1 AND 20 sECONDS AFTER THE GAUGE SIDE WALLS. THE INVENTION ALSO CONCERNS A DEVICE FOR IMPLEMENTING THE PROCESS.
