ANISOTROPY OF CONCRETE AND ITS PRACTICAL IMPLICATIONS

The influence of anisotropy induced by different methods of casting on the uniaxial tensile and compressive strength of concrete cast with the axis of loading vertical is about 8 percent less for tension and 8 percent more for compression than that of corresponding concrete cast horizontally. Consequently, the ratio of tensile to compressive strength for concrete cast with the axis vertical is about 15 percent less than that for corresponding concrete cast horizontally. Some practical situations where a knowledge of these effects should influence the evaluation of concrete quality from tests on standard molded specimens, drilled cores, and sawed beams are also discussed.
