STRENGTH AND DEFORMATION PROPERTIES OF PLAIN CONCRETE SUBJECT TO COMBINED STRESS. PART 3: RESULTS OBTAINED ON A RANGE OF FLINT GRAVEL AGGREGATE CONCRETES
Results are given of an investigation into the influence of mix proportions and specimen age on the strength and stress-strain behavior of flint gravel aggregate concrete in triaxial compression and in tension plus biaxial compression. It is shown that both the water/cement ratio and the aggregate volume concentration have a large influence. A general failure criterian is given in which the major principal stress at failure is expressed as a simple function of minor principal stress, uniaxial compressive strength and estimated uniaxial tensile strength. It is shown that this failure criterion gives a reasonable fit to all the results obtained on the conventional concretes tested. /Author/
