SOME RESULTS FOR THE AVERAGE STRESSES INDUCED IN THE PRINCIPAL COMPONENTS OF CONCRETE

RESULTS ARE OBTAINED FOR THE AVERAGE STRESSES IN THE SEPARATE PHASES OF A RANGE OF CONVENTIONAL CONCRETES. THESE RESULTS SHOW THAT THE LARGER PARTICLES OF AGGREGATE ARE MORE HIGHLY STRESSED THAN THE SMALLER MATERIAL IN THE CONCRETE MIX AND ALSO CONFIRM THAT, FOR A CONCRETE IN UNIAXIAL COMPRESSION, THE CEMENT PASTE OR MORTAR IS IN A STATE OF AVERAGE TRIAXIAL COMPRESSION DURING THE EARLY STAGES OF LOADING. IT IS SUGGESTED THAT THE SIGN OF THE AVERAGE STRESS IN THE SEPARATE PHASES MAY BE USED AS AN INDICATOR OF THE MODE OF FAILURE LIKELY TO OCCUR IN A CONCRETE UNDER ANY PARTICULAR STRESS COMBINATION. RESULTS FOR CONVENTIONAL CONCRETES SUPPORT THIS VIEW AND IT IS CONSIDERED THAT THE INDICATOR WILL ALSO BE USEFUL IN STUDYING THE BEHAVIOR OF HIGH-STRENGTH AND OF LIGHTWEIGHT-AGGREGATE CONCRETES. /AUTHOR/
