CORRELATION OF CONCRETE STRENGTH WITH SCHMIDT HAMMER READINGS

THE MANUFACTURERS OF THE SCHMIDT HAMMER PROVIDE A CHART FOR DETERMINING THE CONCRETE CUBE STRENGTH CORRESPONDING TO A HAMMER READING. TO ASCERTAIN WHETHER THE MANUFACTURERS' CORRELATION CHART IS UNIVERSALLY APPLICABLE, A CORRELATION EXERCISE WAS CARRIED OUT USING RESULTS OF CONCRETE CUBE TESTS AND THE CORRESPONDING HAMMER READINGS. IT IS CONCLUDED THAT THE HAMMER SHOULD BE CALIBRATED WITH THE CONCRETE TO BE USED ON THE JOB. /AUTHOR/
