COMPARISON OF THE DIRECT AND INDIRECT TENSILE TESTS FOR SOIL CEMENT SAMPLES

THIS STUDY OF THE DIFFERENCES BETWEEN DIRECT AND INDIRECT TONSILE TESTS ON SOIL CEMENT SAMPLES WAS CARRIED OUT IN A 10 WEEK PERIOD DURING WHICH TIME A TOTAL OF 156 SAMPLES WERE MANUFACTURED, CURED AND TESTED. DIFFERENCES IN THE VALUES FOR A HEAVY CLAY FROM BARCALDINE IN CENTRAL QUEENSLAND AUSTRALIA HAVE PREVIOUSLY BEEN COMMENTED ON. THE VALUES OF YOUNGS MODULUS IN TENSION AND COMPRESSION WERE THEREFORE CALCULATED AND COMPARED FOR VARIOUS SOIL CEMENT MIXTURES. THE RESULTS OBTAINED ONLY APPLY TO HARMONDSWORTH BRICK EARTH AND THE CEMENT CONTENTS QUOTED. TESTS ARE REQUIRED FOR OTHER SOLS TO CONFIRM CONCLUSIONS REACHED. THE USE OF BASIC ELASTIC THEORY FOR THE DESIGN OF SOIL CEMENT PAVEMENTS IS QUESTIONED. THE INDIRECT TENSILE TEST WHEN COMPARED TO THE STANDARD DIRECT TENSILE TEST GAVE MUCH LOWER RESULTS. A STATISTICAL ANALYSIS OF ALL THE RESULTS OBTAINED IS GIVEN IN THE STUDY. /RRL/A/
