THE EFFECT OF SIZE AND SHAPE OF SPECIMEN UPON THE UNCONFINED COMPRESSIVE STRENGTH OF CEMENT-STABILIZED MATERIALS

AN INVESTIGATION HAS BEEN CARRIED OUT INTO THE EFFECT OF THE SHAPE AND SIZE OF TEST SPECIMEN UPON THE UNCONFINED COMPRESSIVE STRENGTH OF CEMENT-STABILIZED GRAVEL-SAND-CLAY, WELL GRADED SAND AND FINE CRUSHED ROCK. A RANGE OF CEMENT CONTENTS IS USED WITH EACH MATERIAL TO GIVE A RANGE OF STRENGTH UP TO ABOUT 14 N/MM SQUARE AT 7 DAYS. RELATIONSHIPS WERE OBTAINED BETWEEN THE STRENGTH OF CYLINDRICAL SPECIMENS OF DIFFERENT HEIGHT TO DIAMETER RATIOS AND BETWEEN THE STRENGTHS OF CUBES AND CYLINDRICAL SPECIMENS. THE AVERAGE RATIOS OF THE STRENGTH OF CYLINDRICAL SPECIMENS WITH A HEIGHT: DIAMETER RATIO OF 2:1 TO THE STRENGTH OF SPECIMENS WITH A HEIGHT: DIAMETER RATIO OF 1:1 WERE 0.89, 0.74 AND 0.65 FOR 150 MM, 100 MM AND 50 MM DIAMETER SPECIMENS, RESPECTIVELY. THE AVERAGE RATIO FOR THE STRENGTH OF 150 MM. CUBES TO THE STRENGTH OF 300 MM. HIGH BY 150 MM. DIAMETER CYLINDER WAS 1.29, WHICH AGREES CLOSELY WITH THE VALUE OF 4/3 COMMONLY ACCEPTED FOR CONCRETE TEST SPECIMENS. /AUTHOR/
